What happens to energy when it is heated?
When a substance heats up, the rise in temperature makes these particles move faster and bump into each other. Thermal energy is the energy that comes from the heated up substance. The hotter the substance, the more its particles move, and the higher its thermal energy.
What happens when heat is added to a substance?
Heating a substance makes its atoms and molecules move faster. This happens whether the substance is a solid, a liquid, or a gas.
When heat energy goes into a substance one of two things can happen?
When heat (energy) goes into a substance one of two things can happen: 1. The substance can experience a rise in temperature. The heat (the added energy) can be realized as an increase in the average kinetic energy of the molecules.
Where does heat energy go during a phase change?
The heat energy added during the phase change is used to overcome some of the forces that hold the molecules together, allowing them to move further away from each other. During the phase change, the added heat energy is stored as potential energy, or energy of position, as the molecules are now further apart.
