Thermal Energy Review

When air molecules come into direct contact with a warm sidewalk, energy is absorbed through:

• conduction

• convection

• radiation

Thermal energy from the sun is transferred by electromagnetic waves through the vacuum of space.

• conduction

• convection

• radiation

You add ice to a glass of warm water.

• heat will move from the cold ice to the warm water; conduction

• heat will move from the warm water to the cold ice; conduction

• no movement because there is thermal equilibrium

• heat will move from the warm water to the cold ice; convection
