You are sitting by the pool in your bathing suit. There is no wind, and you feel quite warm. After a brief swim, you exit the pool to discover that someone stole your towel. Moreover, the wind is blowing, and you feel very cold. Compare and define the

processes of heat loss from the skin that are occurring before and after your swim.

What will be an ideal response?


Before the swim, heat is being lost from the skin by conduction, which is the transfer of heat from the skin to the surrounding air. After the swim, conduction is still occurring. The skin is wet; thus, evaporation of water will contribute to heat loss. The wind will cause more heat to be lost by convection, in which moving air carries additional heat away from the skin.
