Chapter 2 lesson 2

This occurs when particles gain enough energy to move independently. This results in either evaporation or boiling.

• condensation

• boiling

• freezing

• vaporization

This occurs when vaporized water molecules form bubbles below the surface of a liquid

• boiling

• condensation

• melting

Occurs when particles lose energy and move more and more slowly until they become solid, and fixed in place

• melting

• freezing

• vaporization

Occurs when particles gain enough energy and vibrate so fast they break free from their fixed positions

• melting

• freezing

• condensation

the change in state from a gas to a liquid

• vaporization

• condensation

• melting

This happens when the particles in a liquid gain enough energy to move independently and fill the volume of their container

• condensation

• vaporization

• melting

The change in state from a solid to a liquid

• vaporization

• melting

• condensation

In cold climates, the amount of snow on the ground may decrease even if the temperature stays below freezing. What process best explains this?

• evaporation

• sublimation

• condensation

An uncovered pot of soup is simmering on a stove, and there are water droplets on the wall behind the stove. What can you infer has happened?

• freezing, then thawing

• melting, then boiling

• vaporization, then condensation

The change from a liquid to a solid, or the reverse of melting

• boiling

• condensation

• freezing
