What is supercooling and how is it observed in this experiment? What difference would you see if the solution was not stirred? Solution Super cooling is the process when the temperature is made to come below the freezing point of any liquid without coming into solid state. for eg If freezing of point of water is made to come below 0 degree C without becoming an ice. I am assuming the experiment is just focusing on stirring process that how it will affect the supercooling. When temperature reduces the kinetic energy of the particles also reduces, the particles starts coming closer to each other. If not stirred in between they might get attached or come very close thay may lead to solid state formation. So, stirring helps maintaining the distance between the particles or keeping them in liquid state only. .

Select True or False for each statement: The solubility of gases in water decreases with increasing temperature Most solids are more soluble at higher temperature. Pressure has little effect on the solubility of liquids and solids because they are almost incompressible. Solution a. The solubility of gases in water decreases with increasing temperature. False. Solubility of solutes/solids (sparingly soluble) increases with increase in temperature not gases. Also, at high temperature, water itself starts vaporizing. b. Most solids are more soluble at high temperature. True. This is because the strong intermolecular forces of attraction present in solids gets easily broken at high temperature. This liberates the ions of the crystal lattice and breaks the solid making it more soluble. c. Pressure has little effect on the solubility of liquids and solids because they are almost incompressible. True. Liquids and solids are almost incompressible because the interactions are strong among the molecules and they are quite close to one another. These molecules have very low or negligible pressure which remains constant throughout. Hence it doesn\'t affect their solubilities much. .

What is entropy? What is its significance for engineering devices and processes? Solution Entropy is a thermodynamic quantity representing the unavailability of a system\'s thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system. The entropy of a substance is real physical quantity and is a definite function of the state of the body like pressure, temperature, volume of internal energy. Significance- the significance of entropy revolves around the stability of a system/reaction. the higher the entropy, the more unstable the system/reaction. from the third law of thermodynamics we know that the entropy of a crystalline solid is zero at the absolute temperature (0 K). thus this is the most stable form of a substance. An increase in entropy implies a transition from on ordered to a less ordered state of affair. .

What is an income statement and what information does it communicate? Solution Answer: Income statement:The income statement is one of the three primary financial statements used to assess a companyâ€™s performance and financial position (the two others being the balance sheet and the cash flow statement). The income statement summarizes the revenues and expenses generated by the company over the entire reporting period. Net income=Revenue-Expenses It communicates about: Revenue is the money that a company takes in. Expenses are the money that a company pays out. Net income is the amount of money that is left after a company subtracts their expenses from their revenue. .

What is Contingent Liabilities? Solution Contingent liabilities are those liabilities which are not liabilities as of now. In future they may become liabilities. They are called contingent because they are not real. Example: A bank shows all bank guarantees it has issued as contingent liabilities in its balance sheet. Reason: those bank guarantees may be invoked and may actually become liability in some unknown date in future. Contingent liabilities are mentioned in balance sheet and annual report. There is a solid reason for the same. Suppose any contingent liability becomes a real liability in future then the stake holders in the company should not get surprised by sudden expense by the company. Investors need to be informed of possible liabilities in future. .

What is CORBA? Give a brief Overview. Solution The CORBA, which stands for Common Object Request Broker Architecture which was developed by the Object Management Group (OMG) which is a standard to provide communication among distributed objects. The communication between client and server is accomplished through a well-defined object-oriented interface. The Object Request Broker (ORB) determines the location of the target object, sends a request to that object, and returns any response back to the caller. An Interface Definition Language (IDL) is the OMG standard used define the interface definitions or APIs, which provides a platform independent flexibility. .

What is black box testing? Solution Black Box Testing:- Black box testing refers to the testing of an application or software, it is actually used to test the functionality of the particular software without actually connecting the software to the actual peers,which it will use when it will actually start working. So in other words we can say that is a dummy kind of testing done before launching the Software or the Application to make sure that it is working up to the mark. It is also used to test different stages of the software while it is being build like unit, integration, system and acceptance,that is each virtual layer of testing can be done before the Software or the Application is Released. .

What is an ETL plan that Ralph Kimball identifies from the 34 Subsystems that emphasize the most important within an organization. Solution The Extract-Transform-Load (ETL) system, that Ralph Kimball identifies from the 34 subsytems that emphasize the most important within an organization, is often estimated to consume 70 percent of the time and effort of building a data warehouse. But there hasn\'t been enough careful thinking about just why the ETL system is so complex and resource intensive.I think Everyone understands the three letters: You get the data out of its original source location (E), you do something to it (T), and then you load it (L) into a final set of tables for the users to query.The Ralph Kimball Group has been exposed to hundreds of successful data warehouses. Careful study of these successes has revealed a set of extract, transformation, and load (ETL) best practices. .

What is bit stuffing in CAN messages? Why do we use it ? Solution Bit stuffing is a provider for Error Handling when Transfer Layer instead of Physical Layer in Control Area Network (CAN).A Controller Area Network (CAN bus) is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other in applications without a host computer. It is a message-based protocol, designed originally for multiplex electrical wiring within automobiles, but is also used in many other contexts. It serves two purposes In CAN bit Synchronization happens with an edge. So inserting an edge after 5 consecutive homogeneous bits ensures synchronization of all nodes. When the receiver is receiving homogeneous bits it will not understand whether it is reading the bit. so to avoid resulting Bit error Bit Stuffing is used. .

What is a reasons for using layered protocols? What is one possible disadvantage of using layered protocols? Solution Reasons for using Layered protocols: 1. Layering of protocols provides well-defined interfaces between the layers, so that a change in one layer does not affect an adjacent layer. 2. The protocols of a network are highly complicated and designing them in layers make their implementation more feasible. Possible disadvantage of using Layered Protocol: Each layer potentially puts overhead both in terms of information stored in protocol headers and processing time. .

What is a single entry accounting system? Solution Single entry accounting system is considered as an incomplete system of recording financial transactions. Single entry system maintains only accounts of debtors, creditors and cash book Single entry accounting system is not based on concept of duality and thus is not self balancing. Chances of error are high. Single entry accounting system us generally used by small businesses as there are less formalities, simle to use and less expensive as compared to double emtry system. Single entry system requires less expertise. Single entry system is not preffered as it does not provide data for efficient planning to management, Less likely to detect threats and frauds and thus overall control suffers. .

What is a false positive and how could it be used to hide a real attack? Solution False positives are alerts generated by an IDS because it thinks it has detected a valid attack against a monitored system,but the attack really is not valid.False Positives are problems because they create alert noise that can hide a real attack,and then can send you a wild goos chases for attacks that never relly happened. A False positive occurs when an IDS generates an alert on either Network traffic that looks like an attack to the IDS,but isnot an attack. A real attack that attack doesnot applyto the system being monitored. A false negative is a real attack that was missed by the IDS, and therefore not alerted on.An IDS might miss an attack because the attack is not one it recognizes,becuse the IDS overwhelmed or because the attacker has successfully used a method of evading the IDS. .

What impact does font selection have on readability? Solution Font selection plays a vital role in the readability. With different sizes and types of fonts we differentiate between headings, sub headings and the content of the paragraph. We can even differentiate between the definition, explanation and example of a particular content in particular context. For comfortable reading, we must always choose simple font like Times, Times New Roman,Calibri etc. Fonts can also be used to display the content in artistic way. Usually these font types will be artistic and attractive look and feel but very complex when it comes to the point of readability. In this manner font selection has various impact on readability.some are very simple and soothing which provide ease of readability and some are very complex it terms of readability. .

What if Source One were to argue that it was merely an agent and was only responsible for gathering information... could Source One claim that its client is a principle, and therefore Source One is not responsible for the information request made by the client? Solution The attorney-client privilege has become one of the most complex and therefore, litigated privileges. 1 This is due, in significant part, to the difficulties created by the concept of confidentiality. 2 From the creation and preservation of the privilege, to the development of the facts to prove the legitimacy of the claim, the requirement of confidentiality 3 has created time-consuming and costly responsibilities for both litigants and judges. 4 In addition, confidentiality has been interpreted as imposing a superfluous secrecy requirement that has generated conflicting decisions and practices. .

What does “wave-particle duality” of light mean? What are some of the evidence supporting the wave theory of light? What are some of the evidence supporting the particle theory of light? Solution Wave particle duality means behavior or light both as particle as well as wave in different cases. Photoelectric effect shows the particle nature of light in which light as a packet of photons incidents on a metal and it will eject a photon of energy less then that of incident photon. Young\'s double slit experiment supports the wave nature of light in which interfere of coherent wave sources increase the amplitude and intensity of light. That shows that light have wave like property. .
