KS3 Gas Pressure

Gas pressure is caused by

• Gas molecules heating up

• Gas molecules reacting with other gas molecules

• Gas molecules hitting the walls of a container

• Gas molecules hitting other gas molecules

The pressure of the gas in the balloon in the ice water will be:

• Greater than that of the balloon in the boiling water.

• Less than that of the balloon in the boiling water.

• The same as that of the balloon in the boiling water.

• Not enough information to answer the statement.

Gases have...

• A definite shape and volume

• A definite shape but no definite volume

• No definite shape but a definite volume

• No definite shape or volume

The more collisions with a surface the:

• smaller the gas pressure

• the higher the temperature

• the greater the gas pressure

Which of these is under greater pressure?

• 
• 

The pressure inside the balloon will:

• Decrease

• Increase

• Remain the same

• Not enough information to formulate an answer

Atmospheric pressure:

• Decreases with altitude

• Increases with altitude

• Does not change with altitude

When gas is compressed into a smaller volume:

• the pressure will increase

• the pressure will decrease

• the number of gas particles will decrease

• the pressure will stay the same

If a hairspray can is heated, what can be expected of the pressure of the gas inside the can?

• The pressure will increase

• The pressure will decrease

• The pressure will remain constant

• The pressure will equalize

When a gas in a container is heated:

• the pressure decreases

• the pressure increases

• the particles move slower
