5. Nathan is helping prepare a large meal for a family gathering. After cooking for several hours, he
notices the windows inside the kitchen are covered in moisture. Which answer best explains how this
happened?
A. Evaporated moisture is condensing on the windows.
B. Heating up the house will make moisture evaporate from the windows.
C. It is raining outside and hot and dry inside, so water condenses inside the windows.
D. Having many people in a house causes water to form condensation on the windows.
Explanation:
a. If the absolute humidity of air is 27.6 g/kg,
how many grams of water vapor are there in
the 4.8 kg of air?
b. Air at temperature 20.0°C contains some
water vapor. If the partial pressure of water
vapor is 1.98 kPa, what is the relative humidity of
the air in %? The saturation water vapor
pressure at 20.0°C is 2.34 kPa.
c. If the relative humidity of air is 80 % at 18.0°C,
what is the partial pressure of water vapor in the
air in the unit of kPa? The saturation water
vapor pressure at 18.0°C is 2.07 kPa.
A. Both statements A and B are correct.
B. Statement A is correct, and B is incorrect.
C. Statement A is incorrect, and B is correct.
D. Neither statement A nor B is correct
A. The principle of convection is exemplified by the flow of warm water from the tropics to poles whereby this process helps in the distribution of heat on the surface of the Earth.
B. Temperature is crucial to biomolecules because their physical and chemical properties which determine their functions is directly affected by it.
