Suppose the latent heat of vaporization of H2O were twice its actual value. (a) Other things being equal, would it take the same time, a shorter time, or a longer time for a pot of water on a stove to boil away? (b) Would the evaporative cooling mechanism of the human body be as effective, less effective, or more effective? i need a bone thrown to me on this one. attempt at (a): latent heat of vaporization on water = 22.6e5so twice the actual value would be 4.52e6. to me it would take the same amount of time for the water to boil out because the same about of steam would be produced no matter the boiling point. attempt at (b): i have no clue.
