What happens to particles in a solid?

They vibrate back and forth in place.

How is kinetic energy transferred between particles?

Via collisions between particles.

How does heat energy typically move?

From warmer to cooler matter.

What must happen for an object's temperature to change?

Energy must leave or enter the system.

What increases when more particles are in contact during energy transfer?

Amount of kinetic energy transferred.

What is the process called when liquid water becomes gas?

Evaporation

What causes air near the Earth's surface to rise?

Heat transfer from the ground.

How do water droplets form in clouds?

Through condensation of water vapor.

Why do clouds appear visible?
