Answer to Question 1

ANS: D
In simple terms, for an object with a given emissivity, the larger the surface area (relative to mass) and the lower the surrounding temperature, the greater is the radiant heat loss per unit time.

Answer to Question 2

ANS: B
Vaporization is the change of state from liquid to gas. Vaporization requires heat energy. Ac-cording to the first law of thermodynamics, this heat energy must come from the surroundings. In one form of vaporization, called evaporation, heat is taken from the air surrounding the liquid, thereby cooling the air.
