Physical Science Ch. 3 Review

A substance with definite volume & definite shape is

• a solid
• a liquid
• a gas

A substance with definite volume & no definite shape is

• a solid
• a liquid
• a gas

The graph below shows the temperature and volume change in a gas. Which measurement would be the best prediction for the volume of the gas at a temperature of 500 K?

• 1250 mL
• 1500 mL
• 1750 mL
• 200 mL

What state will bromine be in at room temperature (37*C)?

• solid
• liquid
• gas
• plasma

Most of the matter in the universe is

• a solid
• a liquid
• a gas
• a plasma

What says all matter is composed of tiny particles, these particles are in constant, random motion, the particles collide with each other and with the walls of any container in which they are held, and the amount of energy that the particles lose from these collisions is negligible?

• potential theory
• gravitational theory
• evolutionary theory
• kinetic theory

Which change is endothermic?

• solid to liquid
• liquid to solid
• gas to liquid
• gas to solid

The change from a solid to a gas is called

• evaporation
• melting
• deposition
• sublimation

During a phase change (choose all that apply)

• the temperature of a substance changes.
• the state of the substance changes
• the temperature of a substance does not change.
• the state of the substance does not change.

The energy absorbed by 1 gram of ice as it melts is known as the _____ of water.

• heat of melting
• heat of fusion
• phase change
• vaporization
