Are you asking about a plot of Boyle's Law?

Boyle's Law is

#PV = k# or #P = k/V#

There are three common ways of plotting Boyle's Law: #P# vs. #V#, #P# vs. #"1/"V#, and #PV# vs. #V#.

#P# vs. #V#

A plot of #P# vs. #V# is a hyperbola.

Remember that #(PV)/T = k# or #P = (kT)/V#.

If we increase the temperature, the new value of #kT# will be higher, and the new graph will be above the original plot.

#P# vs. #"1/"V#

Since #P = (kT)/V#, a plot of #P# vs. #"1/"V# is a straight line with a slope #kT# starting at the origin.

If #T# increases, the slope #kT# increases, and the new graph will be above the original plot.

#PV# vs. #V#

A plot of #PV# vs. #V# is a horizontal straight line, because #PV = kT = "a constant"#.

If #T# increases, #kT# increases, and we get a new horizontal line above the original plot.
