  • Identify the three states of matter and their properties
  • Understand how heat energy changes state
  • Name the transitions: melting, freezing, evaporation, condensation
Quick Check

1. When liquid water turns to ice, this process is called:

AEvaporation
BFreezing
CCondensation

2. What is true about gas particles compared to solid particles?

AGas particles are spread far apart and move freely
BGas particles are more tightly packed
CGas particles do not move at all

3. Dry ice goes directly from solid to gas. This is called:
