The document discusses the SI system of measurement. It defines a measurement as having two parts - a number and a unit. The SI system establishes standard units for seven base quantities: meter (length), kilogram (mass), second (time), ampere (electric current), kelvin (temperature), mole (amount of substance), and candela (luminous intensity). SI prefixes are used to denote multiples and submultiples of units, such as kilo, centi, and milli. Conversions within the metric system involve moving the decimal place in the number to change the unit, as shown through examples converting between liters and milliliters, grams and milligrams, and kilograms and milligrams.

heat
There are three main temperature scales - Fahrenheit, Celsius, and Kelvin.

Conversions between the scales can be performed using fixed formulas. Heat is the transfer of thermal energy between objects in contact or at a distance. Heat transfer occurs through conduction, convection, or radiation, with conduction easiest in solids and liquids due to their close particle contact.

measurements
Here are the steps to write a number in standard form:
1. Locate the decimal point in the number.
2. Move the decimal point so that the number is greater than or equal to 1 but less than 10.
3. Count how many places the decimal was moved. If it was moved to the left, the exponent is positive. If it was moved to the right, the exponent is negative.
4. Write the number as the coefficient (the number with 1-9) and 10 with the exponent determined in step 3.
For example:
0.00045 would be written as 4.5 × 10-4

Chapter 1 introduction_to_engineering_ca ta bello
The document provides an introduction to engineering calculations for chemical processes. It discusses key concepts such as units and dimensions, conversion of units between different systems, mass and volume relationships, flow rates, and chemical composition of mixtures. Specifically, it defines units and dimensions, and how they differ. It explains how to convert between different unit systems and perform dimensional analysis. It also discusses density and how it relates mass and volume. It introduces the concepts of mass flow rates and volumetric flow rates. Finally, it covers ways to express the composition of mixtures, including using mole fractions and mass fractions.

chemistry chapter 03 (all sections in one powerpoint)
This document provides an overview of key concepts from a chemistry textbook chapter on matter, including its properties, changes, mixtures, and elements/compounds. It discusses the three states of matter and defines physical and chemical properties. It also describes two types of changes matter can undergo (physical vs. chemical) and techniques for separating mixtures. Finally, it defines elements and compounds, and explains how they are organized in the periodic table according to atomic structure. The chapter assessments cover identifying properties, states of matter, and distinguishing between mixtures, elements and compounds.
Chemisty chapter 1 notes
This document provides an overview of key concepts in chemistry. It discusses the differences between observations and inferences, and emphasizes recording observations rather than inferences in lab exercises. It also covers scientific methodology, including variables, controls, and the scientific method. Measurement concepts like accuracy, precision, error, and significant figures are defined. Formulas for calculating percent error are presented. Key terms like independent and dependent variables are introduced.
Equipment
This document lists and describes common lab equipment used in chemistry including beakers, Erlenmeyer flasks, graduated cylinders, test tubes, burners, clamps, and more. It explains what each piece of equipment is used for, such as holding liquids (beakers), measuring volumes (graduated cylinders), heating substances (Bunsen burners), and securing items to ringstands (clamps). Safety notes are also provided about proper use and handling of some equipment.
Lab safety
This document outlines several important safety guidelines for working in a lab, including always wearing safety goggles to prevent eye injuries from chemicals or flying objects. Long hair and loose clothing must be secured, and food/drink, backpacks, and horseplay are prohibited in the lab. The location of safety equipment like eyewash stations and fire extinguishers should be known. Proper handling of chemicals, heating procedures, and cleaning of spills are also covered. Any injuries must immediately be reported to the instructor.
Sig figs.ppt
This document discusses uncertainty in measurement and significant figures. It explains that measurements have uncertainty due to limitations of instruments. Precision refers to the agreement between repeated measurements while accuracy is the agreement with the true value. There are two types of errors - random errors that can be high or low, and systematic errors that are always in the same direction. The document provides rules for determining the number of significant figures in measurements and calculations, including how significant figures are treated in addition, subtraction, multiplication and division.
Scientific notation
Scientific notation is a method used to write very large or small numbers in a standardized form. It expresses numbers as the product of a number between 1 and 10 and a power of 10. This allows easier calculations with numbers that would otherwise be difficult to work with in standard form due to the number of zeros. Some key points covered are:
- Scientific notation is written as M x 10n, where 1 ≤ M < 10 and n is an integer exponent.
- When adding or subtracting terms with the same exponent, we simply add or subtract the leading numbers and keep the exponent.
- For terms with different exponents, we move the decimal in the number with the smaller exponent to equalize the exponents
Sig figs practice
This document discusses significant figures and how to determine the number of significant figures in measurements and calculations. It provides examples of counting significant figures in given values. It also summarizes the rules for determining significant figures in addition, subtraction, multiplication and division calculations. Specifically, for multiplication and division the number of significant figures in the result equals the number in the least precise measurement. For addition and subtraction, the number of decimal places in the result equals the number in the least precise measurement.
Chapter 2 chemistry revised
The document discusses various topics in science including derived units, percent error, scientific notation, significant figures, rounding numbers, and graphing. It defines key terms such as derived units, density, error, scientific notation, and significant figures. Rules are provided for determining significant figures, rounding numbers, and ensuring calculations maintain the appropriate number of significant figures. Graphs are described as a way to visually display data and relationships between variables.
Blank periodictable
The blank periodic table of the elements is an image showing the layout of the periodic table without any element names or properties filled in. It contains the standard 18 columns and 7 rows that organize the 118 known elements based on their atomic structure and properties. This blank template can be used to learn or review the elements and their placement on the periodic table.
