Front

What happens when ice cubes melt in a glass?

Back

Heat is transferred from the warmer water to the ice cubes.

Front

What is thermal energy?

Back

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

Front

What is the difference between temperature and thermal energy?

Back

Temperature measures the average kinetic energy of particles, while thermal energy is the total energy.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids and gases).

Front

What is radiation?

Back

The transfer of heat through electromagnetic waves.

Front

What happens to the thermal energy of an object when it is heated?

Back

It increases as the particles move faster.
