Question
Chapter 11, Problem 149RQ
Interpretation Introduction
Interpretation:
The reason is to be explained for the formation of clouds when the humid air of a weather system called a warm front encounters the cool, relatively dry air of a cold front.
Concept Introduction:
When two phases of a substance come in contact with each other, heat transfer takes place, which causes the highly energetic phase to cool down and lower energy phase to get heated up.

22) Evaporation of sweat requires energy and thus take excess heat away from the body. Some of the water that you
drink may eventually be converted into sweat and evaporate. If you drink a 20-ounce bottle of water (590g) that
had been in the refrigerator at 3.8 °C, how much heat is needed to convert all of that water into sweat and then to
vapor? (Note: Your body temperature is 36.6 °C. For the purpose of solving this problem, assume that the therm
properties of sweat are the same as for water.
Us, liquid water =
4.184 J/g °C
Cs, steam= 1.84 J/g °C
