Best answer


You can change an object鈥檚 state of matter by adding or removing thermal energy. When you add thermal energy to an object these things can happen:Particles move faster(increased kinetic energy). Particles get farther apart (increased potential energy).

  • What happens to thermal energy when matter changes state?

  • When a given piece of matter undergoes a state change, thermal energy is either added or removed but the temperature remains constant. When a solid is melted, for example, thermal energy is what causes the bonds within the solid to break apart.

  • What happens when heat is added or removed from a substance?

  • Adding or removing heat from a substance will affect its temperature and thermal heat. Heat however is not the same as the thermal energy and temperature. Thermal energy and temperature are properties of a substance. Heat is the energy involved when these properties change.

  • What is the difference between thermal energy and heat?

  • Heat is measured in two ways: calories and joules Adding or removing heat from a substance will affect its temperature and thermal heat. Heat however is not the same as the thermal energy and temperature. Thermal energy and temperature are properties of a substance. Heat is the energy involved when these properties change.

  • How is thermal energy transferred from one object to another?

  • Thermal energy depends on how many particles are present in the object. Energy as heat will be transferred from the warmer object to the cooler object until both objects are at the same temperature.
