Heat transfer

Front

What is conduction?

Back

The transfer of heat by direct contact between materials.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids or gases) due to differences in temperature and density.

Front

What is radiation?

Back

The transfer of heat in the form of electromagnetic waves, which can occur in a vacuum.

Front

What is temperature?

Back

The measurement of the average kinetic energy of the particles in a substance.

Front

What happens to particles during a phase change?

Back

Particles move at the same speed until more heat or cold is added.

Front

What is thermal energy?

Back

The total kinetic energy of all the particles in a substance.

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between substances due to a temperature difference, while temperature is a measure of the average kinetic energy of particles.

Front

What is an example of conduction?

Back

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

Boiling water; the hot water rises and cooler water sinks, creating a circulation pattern.

Front

What is an example of radiation?

Back

Feeling the warmth of the sun on your skin.
