Back

Lower.

Front

What happens to solid ice when the amount of thermal energy increases?

Back

The ice goes from being a solid to a liquid.

Front

What factors affect the relationship between the temperature of a system and the total energy of the system?

Back

The type, states, and amount of matter in the system.

Back

From Cube #1 to Cube #3.

Front

What is conduction?

Back

The transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

The transfer of thermal energy through the movement of fluids (liquids and gases).
