GAS PRESSURE

How can we increase the gas pressure inside a sealed container?

• Increase the number of particles inside the container
• Increase the temperature
• Decrease the volume of the container
• All of these

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

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.

This is an example of the everyday application of pressure in:

• Solids

• Liquids

• Gases

• Plasma

We can increase the pressure of a gas by:

• Adding more gas.

• Reduce the volume of the container.

• Increase the temperature of the gas.

• None of the above answers.

The reason gases can be compressed is because:

• The particles are very close together.

• The particles are merely vibrating.

• The particles are unable to move.

• The particles are very far apart.

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

What direction do the molecules go in the air?

• everywhere
• no where
• there are no molecules
• downward
