Chemistry

Consider a one acre field with a 100 ft high layer of airexactly over the field. Water vapor condenses and forms a 0.1 mmlayer of dew on the surface of the field. If the air temperaturewas 60 oF when the dew forms, what is the final temperatureof this layer of air (in oF)?

Assumptions and Values:

• Let the surface of the field be perfectly flat.

• Let the air absorb all heat from the formation of the dew.

• Let the heat of vaporization of water be ∆Hvap = 44 kJ mol

• Let the density of the air be ρair = 1.2 kg m3 • Let thespecific heat of the air be Cair = 1.01 J g · oC
