Gas LawsGases are all around us. We are dependent it on them for our survival. As we move through this unit we will learn how pressure, volume, temperature, and moles will describe the nature of the gas and how it behaves. Upon completion of this unit you should be able to answer:

Physical Characteristics of Gases
Upon completion of this unit you should be able to:
Molecular Composition of Gases
- Use the kinetic molecular theory (KMT) to explain how certain physical properties of ideal gases differ from real gases
- Describe the conditions under which real gases deviate from "ideal" behavior
- Explain the five postulates of the kinetic molecular theory.
- Define pressure and standard pressure in terms of force and explain how pressure is measured
- Use the gas laws to express simple mathematical relationships between the pressure, temperature, volume and quantity of gases
- Relate KMT to the individual gas laws
Molecular Composition of Gases
- Develop a relationship between the volume, mass, and number of particles of a gas
- Perform calculations using the ideal gas law, specifically being able to solve for pressure, volume, temperature, or number of moles
- Perform stoichiometric calculations using the relationship between volume and moles both at STP and non STP conditions
- Demonstrate the relationship between the mass of gas particles and their rate of effusion

Day 1 10/3Introduction to properties of glass. Today you will conduct a series of investigation to determine how the pressure, temperature, volume and moles interact
Gas Laws Rotation Activity Watch the following video over kinetic molecular theory and the gas laws. Complete the brief questions on goformative. |
Day 2 10/5Laws and KMT: Today in class you will look at the observations collected from the gas laws rotation activity and begin to develop the gas law, Boyle's, Charles', Gay-Lussac's and Avogadro's. From these laws and observations you will predict the five postulates of the kinetic molecular theory (KMT).
Watch the following video over the ideal gas law. Complete the brief question(s) on goformative. |
Day 3 10/7Ideal Gas Law: Today you will develop the Ideal Gas Law, PV=nRT, and perform calculation of to solve for one of the 4 variables if the other three are known. You will also develop derivations to the ideal gas law. You will also determine when it is appropriate to use the ideal gas law or the combined gas law.
For next class please watch the following video on gas stoich & limiting reactant stoichiometry. Complete the goformative over the video. |

Day 4 10/12
Gas Stoichiometry and Limiting Reactant Stoich: Today you will use stoichiometry to calculate the moles or volume of a gas used or produced in a reaction both at standard state condition, STP, (273 K and 1 atm) and at non-standard state conditions.

Day 5 10/14
Can you calculate R?: We will calculate the root mean square velocity of a gas, as well as use Dalton's Law of Partial Pressures to determine the pressure of a gas. We will also determine the molar mass of carbon dioxide via the collection of gas over water
Lab - Determine the Ideal Gas Constant |
Day 6 10/17
Quiz 2.1: Quiz over lessons 2.1 - 2.5
Bottle Rocket Design Challenge: Today with your group you will design a bottle rocket using the gas laws that is solely powered by pressure. Bottle Rocket Lab |
