(a) The sun radiates 650 W/m? on the surface of a particular lake. At what rate (in mm/hr) would the lake evaporate if all of this energy went to evaporating water? Discuss as many other ways you can think of that this energy can be distributed (hfg for water is 2,257,000 J/kg). Do you suppose much of the 650 W/m² goes to evaporation?

Concept explainers

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Question

(a) The sun radiates 650 W/m? on the surface of a particular lake. At what
