Heat Transfer Review

Front

What is heat transfer?

Back

The process of thermal energy moving 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

The transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

Give an example of conduction.

Back

A frying pan heating up on a stove.

Front

Define convection.

Back

The transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

Give an example of convection.

Back

The warm air rising and cool air sinking in a room, creating a circulation pattern.

Front

Define radiation.

Back

The transfer of heat in the form of electromagnetic waves, such as infrared radiation, without the need for a medium.

Front

Give an example of radiation.

Back

The warmth felt from the sun on your skin.

Front

What is the role of the Gulf Stream in heat transfer?

Back

It is an ocean current that transfers warm water from the tropics to the northern Atlantic, demonstrating convection.

Front

How does atmospheric heating occur?

Back

Through radiation from the sun, conduction with the Earth's surface, and convection in the atmosphere.
