The heat of vaporization of water is 540 cal/g.A soil containing 30 kg water per 100 kg soil solids lost one sixth of that water by evaporation.If one tenth of the energy needed to evaporate the water came from the soil solids how much would the temperature of those solids be lowered? A)5.2^oC B)32.4^oC C)20.5^oC D)10.5^oC E)13.5^oC

Question

Quizplus · Accepted Answer

The energy needed to evaporate the water is calculated using the heat of vaporization. The temperature change is then found using the specific heat capacity of the soil solids and the energy taken from them.

The Heat of Vaporization of Water Is 540 Cal/g
