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

What is conduction?

Back

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

Front

What is convection?

Back

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

Front

What is radiation?

Back

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

Front

How does temperature affect heat transfer?

Back

Heat transfer occurs from areas of higher temperature to areas of lower temperature until thermal equilibrium is reached.

Front

What is an example of conduction?

Back

An example of conduction is when a metal spoon gets hot after being placed in a pot of hot soup.

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking in a room, creating a circulation of air.

Front

What is an example of radiation?

Back

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

Why do metals conduct heat better than wood?

Back

Metals have free electrons that can move easily, allowing them to transfer heat quickly, while wood is an insulator.
