Solution
2) Thermodynamics:
Thermodynamics is the branch of physics that deals with the relationships between heat and
other forms of energy. In particular, it describes how thermal energy is converted to and from
other forms of energy and how it affects matter.
3) Energy :
Measure of the ability of a body or system to do work or produce a change, expressed usually in
joules or kilowatt hours (kWh). No activity is possible without energy and its total amount in the
universe is fixed. In other words, it cannot be created or destroyed but can only be changed from
one type to another.
4) First law of thermodynamics:
The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic
processes are therefore subject to the principle of conservation of energy. This means that heat
energy cannot be created or destroyed. It can, however, be transferred from one location to
another and converted to and from other forms of energy.
5) Second law of Thermodynamics :
The second law of thermodynamics states that the total entropy of an isolated system always
increases over time, or remains constant in ideal cases where the system is in a steady state or
undergoing a reversible process. The increase in entropy accounts for the irreversibility of
natural processes, and the asymmetry between future and past.
6) System :
A thermodynamic system is a quantity of matter of fixed identity, around which we can draw a
boundary.
7)Closed system :
Closed systems exchange energy but not matter with an outside system.
8) Yes, In closed system energy may cross the boundary.
9) Isolated system:
In Isolated system there is no transfer of heat and mass with surroundings.
10) Open systems:
In Open systems there is transfer of both heat and mass with the surroundings.
11) Intesive property:
An intensive property, is a physical property of a system that does not depend on the system size
or the amount of material in the system.
eg: density, pressure and temperature
12) Extensive Property:
An extensive property of a system does depend on the system size or the amount of material in
the system.
eg : volume, internal energy
13 ) continuum :
Anything that goes through a gradual transition from one condition, to a diff.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Thermodynamics
Introduction
Thermodynamics (Greek word thermo means heat and dynamics means
motion) is the branch of science which deals with the study of different
forms of energy and the quantitative relationships between them. The
complete study of thermodynamics is based upon three generalizations
called first, second and third law of thermodynamics. These laws have
been arrived purely on the basis of human experience and there is no
theoretical proof for any of these laws.
Basic concepts
(1) System, surroundings and Boundary: A specified part of the universe
which is under observation is called the system and the remaining portion
of the universe which is not a part of the system is called the
surroundings. The system and the surroundings are separated by real or
imaginary boundaries. The boundary also defines the limits of the system.
The system and the surroundings can interact across the boundary.
(2) Types of systems:
(i) Isolated system: This type of system has no interaction with its
surroundings. The boundary is sealed and insulated. Neither matter nor
2. energy can be exchanged with surrounding. A substance contained in an
ideal thermos flask is an example of an isolated system.
(ii) Closed system: This type of system can exchange energy in the form
of heat, work or radiations but not matter with its surroundings. The
boundary between system and surroundings is sealed but not insulated.
For example, liquid in contact with vapour in a sealed tube and pressure
cooker.
(iii) Open system: This type of system can exchange matter as well as
energy with its surroundings. The boundary is neither sealed nor
insulated. Sodium reacting with water in an open beaker is an example of
open system.
(iv) Homogeneous system: A system is said to be homogeneous when it is
completely uniform throughout. A homogeneous system is made of one
phase only. Examples: a pure single solid, liquid or gas, mixture of gases
and a true solution.
(v) Heterogeneous system: A system is said to be heterogeneous when it
is not uniform throughout, i.e., it consist of two or more phases.
Examples: ice in contact with water, two or more immiscible liquids,
insoluble solid in contact with a liquid, a liquid in contact with vapour,
etc.
(vi) Macroscopic system: A macroscopic system is one in which there are a
large number of particles (may be molecules, atoms, ions etc.
(3) Macroscopic properties of the system:
Thermodynamics deals with matter in terms of bulk (large number of
chemical species) behaviour. The properties of the system which arise
from the bulk behaviour of matter are called macroscopic properties. The
common examples of macroscopic properties are pressure, volume,
temperature, surface tension, viscosity, density, refractive index, etc.
The macroscopic properties can be subdivided into two types,
(i) Intensive properties : The properties which do not depend upon the
quantity of matter present in the system or size of the system are called
intensive properties. Its examples are pressure, temperature, density,
specific heat, surface tension, refractive index, viscosity, melting point,
boiling point, volume per mole, concentration etc.
(ii) Extensive properties : The properties whose magnitude depends upon
the quantity of matter present in the system are called extensive
3. properties. Its examples are total mass, volume, internal energy,
enthalpy, entropy etc. These properties are additive in nature.
Any extensive property if expressed as per mole or per gram becomes an
intensive property.
(4) State of a system and State Variables:
Macroscopic properties which determine the state of a system are
referred to as state variables or state functions or thermodynamic
parameters. The change in the state properties depends only upon the
initial and final states of the system, but it is independent of the manner
in which the change has been brought about. In other words, the state
properties do not depend upon a path followed.
