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

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 or gases) caused by differences in temperature and density.

Front

Define radiation.

Back

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

Front

What happens to heat when a cold pack is applied to a warm body?

Back

Front

What is an example of convection in everyday life?

Back

Smoke rising in a room due to a fire is an example of convection.

Front

Why do you need an oven mitt when handling hot objects?

Back

You need an oven mitt to prevent burns from conduction when touching hot surfaces.

Front

What is the relationship between temperature and heat transfer?

Back

Heat transfer occurs from areas of higher temperature to areas of lower temperature.
