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.

Front

Define convection.

Back

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

Front

Define radiation.

Back

The transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

What happens to the temperature of a substance during heat transfer?

Back

The temperature of the hotter substance decreases while the temperature of the cooler substance increases until thermal equilibrium is reached.

Front

How does a thermos bottle minimize heat transfer?

Back

By using insulation to reduce conduction and convection, and reflective surfaces to minimize radiation.

Front

What is an example of conduction in everyday life?

Back

A metal spoon getting hot when placed in a hot pot of soup.

Front

What is an example of convection in everyday life?

Back

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

Front

What is an example of radiation in everyday life?

Back

Feeling warmth from the sun on your skin.
