Thermal Energy Transfer Practice

Front

What causes fluids that are less dense to rise?

Back

The atoms are moving rapidly.

Front

What is the process called when heat is transferred through electromagnetic waves?

Back

Radiation.

Front

What happens to thermal energy when ice is placed in room temperature water?

Back

Thermal energy from the warmer water moves into the ice cubes through conduction, making the water colder.

Front

What is thermal equilibrium?

Back

When two objects reach the same temperature and stop transferring heat.

Front

Why does ice float in water?

Back

Ice floats because it is less dense than water.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

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

Front

What is an example of conduction?

Back

A metal spoon getting hot when placed in a pot of hot soup.

Front

What is an example of convection?

Back

Warm air rising and cool air sinking in a room.

Front

What is an example of radiation?

Back

Feeling warmth from the sun on your skin.
