Learning Goal:To understand the meaning and the basic applications of pV diagramsfor an ideal gas.As you know, the parameters of an ideal gas are described by theequationPV = nRTwhere p is the pressure of the gas, V is the volume of the gas, 12 isthe number of moles. R is the universal gas constant, and T is theabsolute temperature of the gas. It follows that, for a portion of anideal gas,constant.One can see that, if the amount of gas remains constant, it isimpossible to change just one parameter of the gas: At least one moreparameter would also change. For instance, if the pressure of the gasis changed, we can be sure that either the volume or the temperatureof the gas (or, maybe, both!) would also change.To explore these changes, it is often convenient to draw a graphshowing one parameter as a function of the other. Although there aremany choices of axes, the most common one is a plot of pressure asa function of volume: a pV diagram.pVIn this problem, you will be asked a series of questions related todifferent processes shown on a DV diagram (Figure 1).
