A patient uses an oxygen tank to breathe. At the beginning of your shift, the gauge on the tank shows the internal gas pressure to be 250 psi. At the end of your shift you check the tank again and find the pressure to be 25 psi (psi stands for pounds per square inch; it is another unit of pressure). The number of molecules is directly proportional to the pressure of the system. What proportion of the gas molecules was used?

A gas is in a container of volume V0 at pressure P0. It is being pumped out of the container by a piston pump. Each stroke of the piston removes a volume Vs through valve A and then pushes the air out through valve B as shown in Figure P19.74. Derive an expression that relates the pressure Pn of the remaining gas to the number of strokes n that have been applied to the container. FIGURE P19.74

Consider a pressure versus volume graph, where the different curves represent different processes done on a gas. Starting at the origin to point 1, the pressure and volume are increased to 2913 Pa and 4.25 m³, respectively. From 1 to 2, the gas expands at constant pressure to a volume of 7.25 m³. From 2 to 3, the pressure rises to 4082 Pa. Finally, from 3 to 4, the gas expands again to 10.85 m³. Rank the curves from the most positive to the most negative amount of work done on the gas.

The ideal gas law describes the state of a hypothetical ideal gas, i.e., PV = nRT where P is the pressure in Pascal, V is the volume in liters L, R is the ideal gas constant, T is the temperature in kelvin K, and n is the amount of substance. Suppose a researcher has n = 0.654 moles of neon gas. He observed that T and V are increasing at rates of 3 K/min and 2 L/min, respectively, using the fixed gas constant R= 8.31 J/K.mol, find the rate at which the pressure is changing when V = 12.3 L and T = 447K.
