Question
Pl:1: this was all information that was given to me. If need j would need to look it up online.
Experiment 1: The atmosphere
a) Calculate the mass of air in a typical classroom (50 feet
long, 30 feet wide, 10 feet high) at a temperature of 20 C.
b) Calculate the total mass of Earth's atmosphere, considering
that the air pressure is 14.7 pounds per square inch.
c) Going back to the classroom, let's assume that the relative
humidity if the classroom at 20 C is 50%. What is the
partial pressure of the water vapor in the air? (See the final
problem in HW CH 18). How much water is suspended in
the air in the classroom (in liters)
d) Extrapolating that to the entire Earth (use your answer to a
and b), how much water is there in Earth's atmosphere?
