Heat transfer

Front

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 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 by the movement of fluids (liquids or gases) due to differences in temperature and density.

Front

Define radiation.

Back

The transfer of heat in the form of electromagnetic waves, such as infrared radiation, without the need for a medium.

Front

What is thermal energy?

Back

The total kinetic energy of the particles in a substance, which is related to its temperature.

Front

What is an insulator?

Back

A material that does not conduct heat well, preventing heat transfer.

Front

What is a conductor?

Back

A material that allows heat to pass through it easily.

Front

How does heat transfer occur between two objects?

Back

Heat transfers from the object with a higher temperature to the object with a lower temperature.

Front

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

Back

The particles gain kinetic energy and move faster.
