Amplify - Thermal Energy Review

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in an object, which determines its temperature.

Front

What happens to heat transfer when two objects are touching?

Back

Heat transfer occurs between two objects that are touching if there is a difference in temperature between them.

Front

From which object does energy transfer occur?

Back

Energy will always be transferred from the hotter sample to the colder sample.

Front

What is kinetic energy?

Back

Kinetic energy is the energy that an object has because it is moving.

Front

What is the relationship between temperature and thermal energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance, while thermal energy is the total kinetic energy.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or arrangement.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.

Front

What does a higher temperature indicate about the kinetic energy of particles?

Back

A higher temperature indicates that the particles have more kinetic energy and are moving faster.

Front

What is the effect of heat transfer on the temperature of objects?

Back

Heat transfer will cause the temperature of the hotter object to decrease and the temperature of the colder object to increase.

Front

What is a thermal conductor?

Back

A thermal conductor is a material that allows heat to pass through it easily.
