When the temperature of matter increases the particles...

• speed up and move closer

• speed up and move farther apart

• slow down and move farther apart

• pressure decreases

When a gas forms directly from a solid, skipping the liquid phase. it is called

• sublimation

• condensation

• evaporation

• deposition

Both boiling and evaporation are forms of vaporization. What is the difference between them?

• Boiling liquids have intense heat added to it, evaporating liquids take heat from their environment.

• Boiling happens quickly, evaporation happens slowly.

• Evaporation occurs only at a liquid's surface, boiling occurs throughout the liquid

• All of these reasons
