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

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

Holding a metal spoon in a hot pot; the heat from the pot transfers to the spoon.

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

Boiling water; the hot water rises and cooler water moves down.

Front

Define radiation.

Back

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

Front

Give an example of radiation.

Back

The warmth felt from sunlight on your skin.

Front

How does conduction occur in solids?

Back

In solids, conduction occurs as vibrating particles collide with neighboring particles, transferring energy.

Front

How does convection occur in fluids?

Back

In fluids, convection occurs as warmer, less dense areas rise and cooler, denser areas sink, creating a circulation pattern.
