Involves in direct gas exchange
WebConduction is heat exchange between two surfaces in direct contact. Usually heat exchange by conduction is relatively low. It becomes significant when one lies uninsulated on cold ground, especially if under the influence of vasodilating drugs or alcohol. Convection refers to heat transferred from a surface to a gas or liquid environment.
