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

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

• Solids

• Liquids

• Gases

• Plasma

The pressure inside the syringe will decrease if we move the plunger in:

• Direction A

• Direction B

• We don't have to move the plunger as the pressure will change on its own.

• 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

The temperature of gas is kept the same, while its volume is decreased. The gas pressure increases because its molecules

• Strike the walls with higher velocities

• Strike the walls with large farce

• Strike the walls more frequently

• Are in contact with the walls for a shorter time
