Front

What is the transfer of heat by the movement of currents of liquid or gas?

Back

Convection

Front

How could you turn solid metal into a liquid?

Back

You could heat it.

Front

What causes hot and cold water to become the same temperature once they are combined?

Back

Heat (thermal) energy from the hot water is transferred to the cold water.

Front

How does heat move?

Back

Heat moves from warm places to cooler places.

Back

The transfer of heat through direct contact between materials.

Front

What is radiation?

Back

The transfer of heat in the form of electromagnetic waves.

Front

What is thermal energy?

Back

The total energy of all the particles in an object, related to temperature.

Front

What happens to the particles in a solid when it is heated?

Back

The particles vibrate faster and may eventually break free to become a liquid.

Front

What is an insulator?

Back

A material that does not conduct heat well.
