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 . 0 0 ?atm, and graph " B " ?is a plot of volume ( V ) ?as a function of ( T ) ?for 1 ?mole of a gas at 2 . 0 0 ?atm pressure. How do the slopes of the two graphs differ? please tell me what the slope is of graph a and b and how you calculated both slopes.
