A puddle holds 150 g of water. If 0.50 g of water evaporates from the surface, what is the approximate temperature change of the remaining water? (Lv = 540 cal/g)

Answer 1

heat released=50*heatvaporizatioin
look up the heat of vaporization of water.

Then, set that heat to = 100*specificeheatwater*deltaTemp

solve for deltaTemp
