The diagram represents four processes, labeled A, B, C, and D, that occur when water changes phase. Which two processes decrease the motion of the molecules?

• A and B

• B and C

• C and D

• D and A

During which phase change is heat energy released by a substance?

• liquid to gas

• solid to liquid

• solid to gas

• liquid to solid

The diagram below represents a thermometer. Which principle best explains how this thermometer works?

• A liquid changes to a gas when heated.

• A gas changes to a liquid when heated.

• A liquid expands when heated and contracts when cooled.

• A liquid contracts when heated and expands when cooled.

Which process transfers heat when particles collide in a solid?

• convection

• conduction

• radiation

• evaporation

All matter is made up of

• cells

• atoms

• molecules

• compounds

The diagram represents equal masses of the same substance in three phases. Compared to the shapes and volumes of the gas and liquid, the solid

• has a definite shape and a definite volume

• has a definite shape and no definite volume

• takes the shape of its container and has a definite volume

• takes the shape of its container and has no definite volume

A comparison of the three phases shows that in the sample of the liquid, the atoms have a

• greater force of attraction than the solid and the gas

• greater force of attraction than the gas, only

• weaker force of attraction than the gas, only

• weaker force of attraction than the solid and the gas
