An oscillating fan blows currents of cool air across the surface of a warm body is an example of convection. The body gives off waves of heat from uncovered surfaces is an example of radiation. Body fluid in the form of perspiration and insensible loss is vaporized from the skin, which is an example of evaporation. The body transfers heat to an ice pack, causing the ice to melt, is an example of conduction.
