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 pot handle.

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 a hot air balloon rising.

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

An example of radiation is grilling hamburgers over a charcoal flame.

Front

What is a Convection Current?

Back

A convection current is a circular movement of fluid caused by the rising of warmer, less dense fluid and the sinking of cooler, denser fluid.

Front

How does Convection affect weather patterns?

Back

Convection helps to distribute heat in the atmosphere, influencing weather patterns and creating wind.
