(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?

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.

The sun's intensity at the distance of the earth is 1370 W/m2W/m2. 30%% of this energy is reflected by water and clouds; 70%% is absorbed. What would be the earth's average temperature (in ∘C∘C) if the earth had no atmosphere? The emissivity of the surface is very close to 1. (The actual average temperature of the earth, about 15 ∘C∘C, is higher than your calculation because of the greenhouse effect.) Express your answer to two significant figures and include the appropriate units.
