heat transfer

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 or gases) caused by differences in temperature.

Front

Define radiation.

Back

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

Front

What happens to warmer air in a room?

Back

Warmer air rises because it is less dense than cooler air.

Front

In heat transfer, heat flows from which type of object to which type of object?

Back

Heat always flows from a hotter object to a colder object.

Front

What is an example of conduction?

Back

An example of conduction is holding a metal spoon in a hot pot; the heat from the pot transfers to the spoon.

Front

What is an example of convection?

Back

An example of convection is the warm air rising from a heater and circulating around a room.

Front

What is an example of radiation?

Back

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