What happens to thermal energy when a substance is heated?

Back

When a substance is heated, thermal energy is added, causing the particles to move faster and increasing the temperature.

How does thermal energy affect the kinetic energy of molecules?

Back

As thermal energy increases, the kinetic energy of the molecules also increases, leading to faster movement.

What happens to the thermal energy of ice when it melts?

Back

When ice melts, thermal energy is absorbed, causing the solid ice to change into liquid water.

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases) caused by differences in temperature.
