• Gas molecules colliding with each other and walls of container

• Gas molecules not moving

True or False: Gases can be compressed. 

• True

• False

Which container will have a lower pressure?

• left

• right

• they both have the same pressure

How do gas molecules move? 

• in an orderly fashion 

• constantly and randomly

• in a circular motion

• Decrease

• Increase

• Remain the same

When gas particles bump into something, ...

• they cause pressure

• they cause density

Pressure is

• defined as the mass that an object exerts when at rest.

• not a measurable in gases.

• defined as the number of moles of substance divided by the mass of the substance.

• created by the force of the gas particles impacting the walls of the container.

• Gas particles are elastic and do not attract each other.
• The kinetic energy of gas is dependent on temperature 
• Energy is not lost when gas particles collide with each other or with the walls of the container.
• All of the above

As you go up to high altitudes, the Gas pressure decreases because _________

• The air in the high altitudes are is not compressed

• Because the amount of gas particles are decreasing

• Because the gas particles in high altitudes are less dense

• Because the gas particles are far away to the gravity

When you blow up a balloon, it gets bigger because ...

• pressure increases inside

• pressure decreases inside
