Gas Laws Kinetic Theory

Question 1

What causes pressure of a gas in a container?

Answer 1

Gas particles hitting the sides of a container

Question 2

Using Kinetic Theory state what happens to the pressure if you increase the temperature of a fixed mass gas in a fixed volume container.

Answer 2

Pressure increases

Question 3

Using Kinetic Theory state what happens to the pressure if you decrease the volume of a fixed mass gas at a constant temperature.

Answer 3

Pressure increases

Question 4

Using Kinetic Theory state what happens to the volume if you increase the temperature of a fixed mass gas at a fixed pressure.

Answer 4

volume will increase.

Question 5

Using Kinetic Theory state what happens to the pressure if you decrease the temperature of a fixed mass gas in a fixed volume container.

Answer 5

Pressure decreases

Question 6

Using Kinetic Theory state what happens to the pressure if you increase the volume of a fixed mass gas at a constant temperature.

Answer 6

Pressure decreases

Question 7

Using Kinetic Theory state what happens to the volume if you decrease the temperature of a fixed mass gas at a fixed pressure.

Answer 7

Volume decreases

Question 8

Suggest one place that kinetic theory/model is used.

Answer 8

• Weather balloons
• Car tyres
• Aerosol cans
• Aircraft cabins
• Gas tanks for diving
• Pressurised containers - fire extinguishers
