U9 - Thermal Energy and Temperature

Front

What is temperature?

Back

A measurement of the average amount of kinetic energy of the particles in a sample of matter.

Front

In which direction does heat transfer occur?

Back

Only from warm objects to colder ones.

Front

What is the primary method of heat transfer in boiling water?

Back

Convection.

Front

What is heat?

Back

The transfer of thermal energy between objects.

Front

What happens when a piece of ice at -6°C is placed on ground at 50°C?

Back

Heat transfers thermal energy from the ground to the ice.

Front

What is thermal energy?

Back

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

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids and gases).

Front

What is radiation?

Back

The transfer of heat through electromagnetic waves.

Front

What is the difference between heat and temperature?

Back

Heat is the transfer of thermal energy, while temperature is a measure of the average kinetic energy of particles.
