Body heat is the byproduct of your body's normal metabolism. As energy sources (sugars, fats, proteins) are broken down and metabolized to produce ATP, some of the energy is lost as heat. Cells which require more ATP (such as those exercising or constantly in motion) produce more heat.
Latent body temperature is set by a thermostatic mechanism in the hypothalamus, and is kept within a certain range by complex biochemical mechanisms in your body. The thyroid plays a key role in this function. You can think of the thyroid as the accelerator in a car. It produces thyroid hormone, which in turn sets the basal metabolic rate in the body. Too little thyroid hormone, and you are said to be hypothyroid - your metabolic rate is too slow. Too much and you are hyperthyroid - you are always ramped up and jittery.
Other mechanisms are used to help keep body temperature stable on a day to day basis: your skin is a large part of why you stay a relatively constant temperature.
When your core body temperature rises, blood is flooded through capillaries in the skin - people may say you look "flushed," this is the result of dilated capillaries - working through convection to rid your body of heat.
When your core temperature begins to drop too low, blood is shunted away from the skin to prevent this heat loss. You feel the need to put on more clothes, and you may begin to shiver.
Shivering is a very complicated system by which the brain attempts to rewarm itself to prevent hypothermia. It involves rapidly contracting and relaxing groups of muscles. Muscle movement is a very efficient way to produce heat, as muscles have a very high metabolic rate when exercised.
heat energy is created by the random motion of the particles present in the molecules of the substance which increases the kinetic energy as a result of increase of velocity of intermolecular particles resulting in increase of temperature and producyion of heat.
- Sun's radiation
- Friction between two objects
- Burning of fuels
- Electrical resistance in wires
- Mechanical work or processes like compression or expansion
The fast moving electrons collide with the conductor's atoms which start to vibrate (heat).
Energy have no cause, it is just found, and according the the law :
Energy is nor destroyed neither created, it is just transformed from one form to another. :)

Friction causes mechanical energy to be transformed into what?
Friction causes mechanical energy to be transformed into heat energy.
Friction causes kinetic energy to be coverted into?
Friction causes kinetic energy to be converted into heat energy.
What energy source causes evaporation?
Solar energy is the main energy source that causes evaporation. The heat from the sun provides the energy needed to convert water from liquid to gas, leading to evaporation.
Resistance in wires causes electrical energy to be converted to what energy form?
Resistance in wires causes electrical energy to be converted to heat energy. This is known as Joule heating, where the electrical energy is dissipated as heat due to collisions between electrons and atoms in the wire.
Why does adding heat cause particles to vibrate faster?
Adding heat increases the kinetic energy of the particles in a substance. This increase in energy causes the particles to vibrate faster and move more freely.
What is heat and what causes it?
Friction causes heat. Heat is a source of energy.
Friction causes mechanical energy to be transformed into what?
Friction causes mechanical energy to be transformed into heat energy.
What causes molecules energy that causes them to vibrate?
Heat!
Friction causes kinetic energy to be coverted into?
Friction causes kinetic energy to be converted into heat energy.
What causes photosinthesis?
The heat energy from the sun.
What causes gas to move?
Heat energy.
What energy source causes evaporation?
Solar energy is the main energy source that causes evaporation. The heat from the sun provides the energy needed to convert water from liquid to gas, leading to evaporation.
What is the Energy that causes air particles to move quickly?
Heat energy.
Resistance in wires causes electrical energy to be converted to what energy form?
Resistance in wires causes electrical energy to be converted to heat energy. This is known as Joule heating, where the electrical energy is dissipated as heat due to collisions between electrons and atoms in the wire.
Friction causes what type of kinetic energy?
Heat.
What causes water to evaporate into the atmosphere?
Heat energy.
