The mechanism of ___ causes body heat to be lost through direct contact

Conduction

Water chill, which occurs when clothing or the body gets wet, is an example of a. conduction b. convection- causes cold air molecules that are in immediate contact with the skin to be warmed c. radiation- transfer of heat from the surface of one object to the surface of another without physical contact d. evaporation- process in which liquids changes to vapor
