Heat, Temperature, and Thermal Energy

Front

What happens to hot objects as they cool?

Back

Thermal energy in the object is transferred to the surrounding air.

Front

What is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius?

Back

Specific heat.

Front

What is the purpose of insulation in the walls of a building?

Back

To keep thermal energy from moving through the walls.

Front

Why is good insulation important in winter?

Back

It prevents thermal energy from moving easily from inside the warm home to the cool areas outside.

What is conduction?

Back

When heat transfers from objects that are touching.

Front

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

Front

What is convection?

Back

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

Front

What is radiation in terms of heat transfer?

Back

The transfer of heat through electromagnetic waves.
