What is Compressibility?
Measure of how much the volume of matter decreases under pressure

3. Properties of Gases 200 Why are gases easily compressed?
Because of the space between gas particles

4. Properties of Gases 300
What happens to a balloon if taken outside in a cold winter day?
The volume decreases

5. 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

6. Properties of Gases 500
What are the three factors that affect gas pressure

decreases

8. 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.

1.8 L

12. Ideal gases 100 Describe an ideal gas
Particles have no volume; there are no attractions; collisions are elastic

13. 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

14. 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

15. Ideal gases 400 8.31 X L X kPa / K X mol

3.60 X 10^2 kPa

17. Gases mixtures and movements 100
What is effusion?
Movement of molecules in a gas.

18. 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.

19. 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.

20. 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
