Heat transfer-Conduction Convection Radiation

Front

What is heat transfer?

Back

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

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

Define convection.

Back

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

Front

Define radiation.

Back

Radiation is the transfer of heat through electromagnetic waves, without the need for a medium.

Front

How does heat transfer occur in a microwave?

Back

Heat transfer in a microwave occurs through radiation.

Front

What happens to the temperature of an object when it absorbs heat?

Back

The temperature of the object increases when it absorbs heat.

Front

What is an example of conduction in everyday life?

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 in everyday life?

Back

An example of convection is when warm air rises and cool air sinks, creating a breeze.

Front

What is an example of radiation in everyday life?

Back

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