Mobile App Problem 30
The pressure on top of Mount Everest averages about \(235 \mathrm{~mm}\) Hg. Convert this pressure to: (a) torr (b) pounds per square inch (c) inches of mercury (d) atmospheres
Problem 31
The U.S. record for highest recorded barometric pressure is \(31.85\) in. Hg, set in 1989 in Northway, Alaska. Convert this pressure to: (a) millimeters of mercury (b) atmospheres (c) torr (d) kilopascals
Problem 32
The world record for lowest pressure (at sea level) was \(652 \mathrm{~mm} \mathrm{Hg}\), inside of Typhoon Tip, 300 miles west of Guam on October 12,1979 . Convert this pressure to: (a) torr (b) atmospheres (c) inches of mercury (d) pounds per square inch
Problem 33
A sample of gas has an initial volume of \(3.95 \mathrm{~L}\) at a pressure of \(705 \mathrm{~mm} \mathrm{Hg}\). If the volume of the gas is increased to \(5.38 \mathrm{~L}\), what is the pressure? (Assume constant temperature.)
Problem 34
A sample of gas has an initial volume of \(22.8 \mathrm{~L}\) at a pressure of \(1.65 \mathrm{~atm}\). If the sample is compressed to a volume of \(10.7 \mathrm{~L}\), what is its pressure? (Assume constant temperature.)
Problem 35
A snorkeler with a lung capacity of \(6.3 \mathrm{~L}\) inhales a lungful of air at the surface, where the pressure is \(1.0\) atm. The snorkeler then descends to a depth of \(25 \mathrm{~m}\), where the pressure increases to \(3.5 \mathrm{~atm}\). What is the capacity of the snorkeler's lungs at this depth? (Assume constant temperature.)
Problem 36
A scuba diver with a lung capacity of \(5.2 \mathrm{~L}\) inhales at a depth of \(45 \mathrm{~m}\) and a pressure of \(5.5\) atm. If the diver were to ascend to the surface (where the pressure is \(1.0 \mathrm{~atm}\) ) while holding her breath, to what volume would the air in her lungs expand? (Assume constant temperature.)
Problem 39
A balloon with an initial volume of \(3.2 \mathrm{~L}\) at a temperature of \(299 \mathrm{~K}\) is warmed to \(376 \mathrm{~K}\). What is its volume at \(376 \mathrm{~K}\) ?
Problem 45
A 0.12-mol sample of nitrogen gas occupies a volume of \(2.55 \mathrm{~L}\). What is the volume of \(0.32 \mathrm{~mol}\) of nitrogen gas under the same conditions?
Problem 46
A \(0.48\)-mol sample of helium gas occupies a volume of \(11.7 \mathrm{~L}\). What is the volume of \(0.72\) mol of helium gas under the same conditions?
