What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a difference in temperature.

Front

What are the three main types of heat transfer?

Back

The three main types of heat transfer are conduction, convection, and radiation.

Front

Define conduction.

Back

Conduction is the transfer of heat through direct contact between materials.

Front

Give an example of conduction.

Back

An example of conduction is an ice cube melting in a person's hand.

Front

Define convection.

Back

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

Front

Give an example of convection.

Back

An example of convection is warm air rising and cooler air sinking in a room.

Front

Define radiation.

Back

Radiation is the transfer of heat through electromagnetic waves, such as sunlight.

Front

Give an example of radiation.

Back

An example of radiation is the warmth felt from the sun on a sunny day.

Front

What happens to the temperature of an object when it absorbs heat?

Back

The temperature of the object increases when it absorbs heat.

Front

What happens to the temperature of an object when it loses heat?

Back

The temperature of the object decreases when it loses heat.
