Front

What is thermal energy?

Back

The total amount of kinetic and potential energy of all the particles in an object.

Front

What is temperature?

Back

The measure of the kinetic energy of the particles in an object.

Front

Does heat transfer occur from cold objects to warm objects?

Back

No, heat transfer occurs only from warm objects to colder ones.

Front

Is heat a form of energy?

Back

Yes, heat is energy.

Front

What does the symbol '°C' represent?

Back

Celsius.

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between objects, while temperature is a measure of the average kinetic energy of particles in an object.
