Heat Transfer

Front

What is heat transfer?

Back

The movement of thermal energy from one object or substance to another.

Front

What are the three mechanisms of heat transfer?

Back

Conduction, Convection, and Radiation.

Front

Define conduction.

Back

The transfer of thermal energy from one particle of matter to another through direct contact.

Front

Give an example of conduction.

Back

Touching a hot stove and feeling the heat on your hand.

Front

Define convection.

Back

The transfer of thermal energy by the movement of a fluid (liquid or gas).

Front

Give an example of convection.

Back

Boiling water where hot water rises and cooler water sinks.

Front

What are convection currents?

Back

The movement of a fluid caused by differences in temperature that transfers heat from one part of the fluid to another.

Front

Define radiation.

Back

The transfer of energy by electromagnetic waves.

Front

Give an example of radiation.

Back

The warmth felt from the sun on your skin.

Front

What is thermal energy?

Back

The total kinetic energy of particles in a substance.
