Answer:

Heat usually is one of the forms of energy produced in energy transformations. The law of conservation of energy states that energy cannot be created or destroyed; it can only change form. The total energy doesn't change when an energy transformation occurs
Heat is the transfer of thermal energy between objects that have different temperatures. Thermal energy always moves from an object with a higher temperature to an object with a lower temperature. When thermal energy is transferred in this way, the warm object becomes cooler and the cool object becomes warmer.
Heat is absorbed with rise in temperature when change of state is taking place. The configuration of molecules and therefore, the potential energy of the molecules of there is different in two different states say solid and liquid or liquid and gas etc.
Humans are hot-blooded and their body temperature is maintained constant at about 37C, the heat produced in the body has to be given off to the outside. This is done through breathing, sweating and radiating away heat energy to cooler surroundings, say at 20C.
-7. Heat can be transferred in three ways: by conduction, by convection, and by radiation. Conduction is the transfer of energy from one molecule to another by direct contact.

8. Conduction is heat transfer between two objects that are touching each other. When two objects touch and one has a higher temperature than the other; heat is transferred to the object with the lower temperature. When you touch something hot it feels hot because heat is being transferred from the object to your hand.

9. convection

The three types of heat transfer

Heat is transfered via solid material (conduction), liquids and gases (convection), and electromagnetical waves (radiation).

10. heat is transmitted through space by radiation, but space has a temperature because it isn't truly empty. Or, better, it is not space that has a temperature at all, but the (very sparse) light and matter found in space. Transmitting heat is not the same thing as having a temperature.
