How heat energy is lost or gained by animals.
- Conduction is the transfer of heat energy from hotter to the cooler of two objects in contact with each other.
- Radiation is the heat transfer from a hot body to a cool one that are not in contact. It is a major source of heat loss.
- Evaporation is change of a liquid to a vapour, it is accompanied by cooling. This is the cause of cooling accompanied by sweating.
- Convection: is the movement of air resulting from local pockets of warm air being replaced by cooler air, and vice vasa. The air movement speeds up loss of heat by radiation and evaporation.
