Examples of Heat Energy

The caloric energy It is a type of energy that bodies have when they are exposed to the effect of heat. It is also called thermal or heat energy, and it is precisely what causes the atoms that make up the molecules to be in constant motion, either moving or vibrating. For example: solar panels, gas oven, microwave.

Every time a body receives heat, the molecules that are part of the object acquire this energy, which generates greater movement. This is one relationship between heat energy and temperaturewhich in any case does not go both ways: if the temperature of an element is increased, its thermal energy increases, but not always when the thermal energy of a body is increased, its temperature increases since in phase changes the temperature is maintained .

The production of heat energy is given in natural form by the sun, and also in artificial form by any fuel, including electricity, gas, coal, oil and bio-diesel. In any case, it is not efficient to generate thermal energy from these fuels.

Uses of heat energy

There are many applications for this type of energy, which are usually divided between domestic and industrial.

  • domestic application. It is mainly limited to heating water through solar thermal panels, or to heating rooms with underfloor heating.
  • industry application. It is mainly associated with the washing and drying of different types of products: the cleaning process of industrial laundries or parts, cars or other types of industrial product.

Transmission: radiation, conduction and convection

One of the most important questions regarding heat energy is its transmission, which follows the laws of thermodynamics in three different ways:

  • by radiationbeing transmitted through electromagnetic waves.
  • by driving when a hot body is in physical contact with a colder body.
  • by convection when hot molecules are moved from one side to the other.

Examples of heat energy transmission

  1. Solar energy panels.
  2. Microwave.
  3. Ice in a cup of hot water, which melts through heat conduction.
  4. Convective heat transfer generated by the human body when a person is barefoot.
  5. Solar ultraviolet radiation, the process that determines the earth’s temperature.
  6. The stove.
  7. The gas oven.
  8. The heat emitted by a radiator.
  9. The generating sets, which with a fossil fuel engine replace the supply of electrical energy.
  10. Most heating systems.
