How much body heat is lost through radiation? Where is the primary location?

List four methods of heat exchange
Convection
Evaporation
Radiation
Conduction
Convection
the process of losing heat through the movement of air or water molecules across the skin ex.) use of a fan to cool off the body is one example
Evaporation
the process of losing heat through the conversion of water to gas
ex.) evaporation of sweat
Radiation
a form of heat loss through infrared rays; involves the transfer of heat from one object to another with no physical contact involved.
ex.) sun transfers heat to earth through radiation
Conduction
the process of losing heat through physical contact with another object or body
ex.) if you sit on a metal chair, the heat from your body would transfer to the cold metal chair
