suppose graph $"$A$"$ is a plot of volume $($V$)$ as a function of temperature $($T$)$ for a $1$ mole of a gas at a pressure of $1\mathrm{.}00$ atm, and graph $"$B$"$ is a plot of volume $($V$)$ as a function of $($T$)$ for $1$ mole of a gas at $2\mathrm{.}00$ atm pressure. How do the slopes of the two graphs differ?
