Heat & 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 main methods 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 differences in temperature.

Front

Define radiation.

Back

The transfer of energy through electromagnetic waves, which can occur in a vacuum.

Front

What is an example of conduction?

Back

Heating a pan on a stove.

Front

What is an example of convection?

Back

Boiling water where hot water rises and cooler water sinks.

Front

What is an example of radiation?

Back

Warming yourself by a fire or sunlight.

Front

How does heat flow between objects?

Back

Heat flows from a hotter object to a cooler object until thermal equilibrium is reached.

Front

What happens to particles in a substance when it is heated?

Back

The particles gain energy, move faster, and usually spread apart.
