What is Compressibility? Properties of Gases 100 What is Compressibility? Measure of how much the volume of matter decreases under pressure
Properties of Gases 200 Why are gases easily compressed? Because of the space between gas particles
Properties of Gases 300 What happens to a balloon if taken outside in a cold winter day? The volume decreases
Properties of Gases 400 If a gas is compressed from 4L to 1L and the temperature remains constant, what happens to the pressure The pressure quadruples
Properties of Gases 500 What are the three factors that affect gas pressure Amount of gas, volume, and temperature
The gas laws 100 IF THE TEMPERATURE IS CONSTANT AS THE PRESSURE OF GAS INCREASES, WHAT HAPPENS TO THE VOLUME? decreases
What does the Charles’s law state? The gas laws 200 What does the Charles’s law state? Volume of a fixed mass is directly proportional to kelvins temperature if the pressure remains constant.
Write the mathematical equation for Charles’s law The gas laws 300 Write the mathematical equation for Charles’s law V1/T1 = V2/T2

The gas laws 500 Calculate the volume of a gas in (L) out of the pressure of : 1x10^2 kPa if its volume at 1.2 X10^2 kPa is 1.5X 10^3mL 1.8 L
Ideal gases 100 Describe an ideal gas Particles have no volume; there are no attractions; collisions are elastic
How do real gases differ from an ideal gas? Ideal gases 200 How do real gases differ from an ideal gas? Low tempreratures and high pressure
Ideal gases 300 What is the volume occupied by 1.24 mol of a gas at 35 ºC if the pressure is 96.2 kPa 33 L
Ideal gases 400 8.31 X L X kPa / K X mol What is the ideal gas constant ? 8.31 X L X kPa / K X mol
Ideal gases 500 If 450 g of methane gas (CH4) is in a 2.00L container at 35Cº, what is the pressure in the container 3.60 X 10^2 kPa
Gases mixtures and movements 100 What is effusion? Movement of molecules in a gas.
Gases mixtures and movements 200 If gases of lower molar mass diffuse and effuse faster, what happens to gasses with higher molar mass? They diffuse and effuse slower.
Gases mixtures and movements 300 What is Graham’s law of diffusion? Dalton’s law states that at constant volume and temperature the total pressure exerted by the mixture of gases is equal to the sum of the partial pressures of the component gases.
Gases mixtures and movements 400 In a mixture of gases, how is the total pressure determined? The sum of the partial pressures of the gases
Gases mixtures and movements 400 What expression relates the mass and the velocity of an object to its kinetic energy? KE = ½ MV^2
