No Definite Shape and No Definite Volume

• Gas
• Liquid
• Solid

Phase change from a solid to a gas.

• sublimation
• deposition
• condensation
• evaporation

When the temperature of matter decreases the particles ...

• speed up and move farther apart
• speed up and move closer together
• slow down and move farther apart
• slow down and move closer together

A gas

• has a definite shape but no definite volume
• has a definite volume but no definite shape
• has fast-moving particles

During a phase change, the temperature

• increases
• decreases
• fluctuates
• stays the same
