Answer 2

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.

Answer 3

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.

Answer 4

The fast moving electrons collide with the conductor's atoms which start to vibrate (heat).

Answer 5

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. :)
