HMH Energy I 2.2 Temperature and Heat

Front

As the kinetic energy of the molecules in a substance increases, what happens to the temperature of the substance?

Back

The temperature of the substance increases.

Front

What happens to the particles in a substance as they cool down?

Back

The particles slow down.

Front

What is temperature a measure of?

Back

Temperature is a measure of the average kinetic energy of molecules in a substance.

Front

What is a device used for measuring temperature called?

Back

A thermometer.

Front

What is the process called when heat is transferred through the movement of fluids?

Back

Convection.

Front

What is the relationship between kinetic energy and temperature?

Back

As kinetic energy increases, temperature increases; as kinetic energy decreases, temperature decreases.

Front

What is the difference between temperature and heat?

Back

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

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of heat in the form of electromagnetic waves.
