On a warm day when the air temperature is , a metal can is slowly cooled by adding bits of ice to liquid water in it. Condensation first appears when the can reaches . What is the relative humidity of the air?
Air is oxygen.
Find the minimum atmospheric pressure that gives a relatively safe partial pressure of oxygen of 0.16 atm.
What is the minimum pressure that gives a partial pressure of oxygen above the quickly fatal level of 0.060 atm?
Find the density of air at a pressure of 1.00 atm and a temperature of , assuming that air is N2, O2, and Ar.
Find the density of the atmosphere on Venus, assuming that the atmosphere is CO2 and N2, with a temperature of 737 K and a pressure of 92.0 atm.
