Amplify Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in an object.

Front

What happens to thermal energy when two objects at different temperatures touch?

Back

Thermal energy transfers from the hotter object to the colder object until they reach the same temperature.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state reached when two objects in contact have the same temperature and no heat flows between them.

Front

How do molecules behave at higher temperatures?

Back

At higher temperatures, molecules move faster and have more kinetic energy.

Front

What is the direction of heat transfer?

Back

Heat always transfers from the hotter sample to the colder sample.

Front

What does it mean if two samples have the same temperature?

Back

If two samples have the same temperature, there is no net heat transfer between them.

Front

Can molecules in a hot sample have less kinetic energy than those in a cold sample?

Back

No, molecules in a hot sample cannot have less kinetic energy than those in a cold sample.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. In the context of thermal energy, it refers to the motion of molecules.

Front

What occurs when a hot object and a cold object are placed in contact?

Back

When a hot object and a cold object are placed in contact, heat flows from the hot object to the cold object.

Front

What is the relationship between temperature and kinetic energy?

Back

The temperature of an object is directly related to the average kinetic energy of its molecules.
