Thermal Energy and Heat Flashcard

Front

What happens to the average kinetic energy of particles in an object when they begin to move quickly?

Back

The average kinetic energy increases.

Front

What happens to the temperature of an object when the average kinetic energy of its particles increases?

Back

The object's temperature rises.

Front

What is the true statement about heat transfer?

Back

Warmer objects always heat cooler objects.

Front

When measuring the temperature of an object, what are you measuring?

Back

The average kinetic energy of its particles.

Front

What is thermal energy?

Back

The total energy of the particles that make up a system.

Front

What is heat?

Back

Thermal energy that flows from something at a higher temperature to something at a lower temperature.

Front

What is the relationship between temperature and kinetic energy?

Back

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

Front

What is specific heat?

Back

The amount of heat required to raise the temperature of one gram of a substance by one degree Celsius.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

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