High heat of vaporization example
WebThis program begins by defining heat of vaporization is the amount of heat that must be added or given off to vaporize one gram or kilogram of a substance an... WebThe cooling effect of perspiration evaporation makes use of the very large heat of vaporization of water. This heat of vaporization is 540 calories/gm at the boiling point, but is even larger, 580 cal/gm, at the normal skin temperature. If the rate of evaporation of perspiration is gm/day = gm/hr. then the cooling rate is Q/t = watts.
