Question
Learning Goal:
To understand the meaning and the basic applications of pV diagrams
for an ideal gas.
As you know, the parameters of an ideal gas are described by the
equation
PV = nRT
where p is the pressure of the gas, V is the volume of the gas, 72 is
the number of moles, R is the universal gas constant, and T is the
absolute temperature of the gas. It follows that, for a portion of an
ideal gas,
One can see that, if the amount of gas remains constant, it is
impossible to change just one parameter of the gas: At least one more
parameter would also change. For instance, if the pressure of the gas
is changed, we can be sure that either the volume or the temperature
of the gas (or, maybe, both!) would also change
pV
To explore these changes, it is often convenient to draw a graph
showing one parameter as a function of the other. Although there are
many choices of axes, the most common one is a plot of pressure as
a function of volume: a pV diagram.
