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

Forces of attraction limit the motion of particles most in

• a solid
• a liquid
• a gas
• both b and c

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

Boyle's Law states that the volume of a gas is inversely proportional to its pressure if the

• temperature and number of particles are constant
• temperature reaches absolute zero
• number of particles decreases
• temperature and number of particles are doubled

At a temperature of 274K, the gas in a cylinder has a volume of 4.0 liters. If the volume of the gas is decreased to 2.0 liters, what must the temperature be for the gas pressure to remain constant?

• 137 K
• 378 K
• 273 K
• 556 K

The phase change that is the reverse of condensation is

• freezing
• sublimation
• vaporization
• melting
