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

Walking on warm sand with bare feet is an example of conduction.

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

Warm air rising near the ceiling of a room is an example of convection.

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 heat from a lamp warming a lizard is an example of radiation.

Front

Which heats up faster, sand or water?

Back

Sand heats up faster than water.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange heat, meaning they are at the same temperature.
