Ninety-nine percent of all matter that can be observed in the universe exists as

• gasses

• plasmas

• liquids

• solids

If you could move a substance from one container to another and its volume changes, the substance is a

• solid

• liquid

• gas

• solution

Collisions of helium atoms and the walls of a closed container cause

• condensation

• gas pressure

• a decrease in volume

• an overall loss of energy

Raising the temperature of a gas will increase its pressure IF the volume of the gas

• and the number of particles are increased

• is increased, but the number of particles is constant

• and the number of particles are constant

• is constant, but the number of particles is increased

Which of the following will cause a decrease in pressure?

• lowering the temperature

• reducing the volume

• adding more gas

• both a and b
