Front

What happens to the thermal energy of an object as its temperature rises?

Back

The thermal energy of the object increases.

Front

What is the property of an object that relates to the average kinetic energy of its particles?

Back

Temperature.

Front

What is the term for the increase in volume of a material due to a temperature increase?

Back

Thermal expansion.

Front

What is the transfer of thermal energy due to a temperature change called?

Back

Heat.

Front

What causes heat to transfer from one object to another?

Back

A difference in temperature.

Front

Define thermal energy.

Back

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

Front

What is kinetic energy?

Back

The energy of an object due to its motion.

Front

How does temperature relate to kinetic energy?

Back

Higher temperature means higher average kinetic energy of particles.

Front

What is specific heat?

Back

The amount of heat required to raise the temperature of 1 kg of a substance by 1°C.

Front

What is the relationship between thermal energy and mass?

Back

For a given temperature, more mass means more thermal energy.
