(a)
Interpretation:
To interpret the fact that when the propane is put under pressure it can be liquefied.
Concept Introduction:
When a gas is pressurized, the molecules of gas come closer. The intermolecular forces pull molecules together, forming a liquid. This results in a change of phase from gas to liquid.
(b)
Interpretation:
The kilogram of propane in full tank should be determined.
Concept Introduction:
A conversion factor is a numerical ratio which is used to show a measurement in one unit as another unit. It is always equal to 1.
To solve this problem, the following conversion factor is used:
(c)
Interpretation:
The number of moles of propane of full tank should be determined.
Concept Introduction:
The number of moles of any substance is related to mass and molar mass as follows:
Here, m is mass and m is molar mass.
(d)
Interpretation:
The volume of flexible container containing propane should be determined.
Concept Introduction:
The ideal gas equation is as follows:
Here, p is pressure of the gas, v is volume of the gas, n is number of moles, r is gas constant and t is temperature.

Each 10. m (approximately 33 ft) of water exerts an additional pressure of 1 atm on the body. (a) What is the pressure on the body at a depth of 100. ft? (b) The partial pressure of nitrogen gas in air at 1 atm is 593 mm Hg. Assuming a SCUBA diver breathes compressed air, what is the partial pressure of nitrogen entering the lungs from a breathing tank at a depth of 100. ft? (c) The partial pressure of oxygen gas in the air at 2 atm is 158 mm Hg. What is the partial pressure of oxygen in the air in the lungs at a depth of 100. ft?
