Heat Transfer

Front

What is heat transfer?

Back

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

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 touching a hot stove and feeling the heat on your hand.

Front

Define convection.

Back

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

Front

Give an example of convection.

Back

An example of convection is the rising of warm air in a room, which creates a circulation pattern.

Front

Define radiation.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

Give an example of radiation.

Back

An example of radiation is feeling the warmth of the sun on your skin.

Front

How does heat transfer occur in a lava lamp?

Back

In a lava lamp, heat causes the colored liquid to expand, become less dense, and rise, demonstrating convection.

Front

What type of heat transfer occurs when you feel warmth from a heat lamp without touching it?

Back

This is an example of radiation.
