Pressure versus temperature graph of an ideal gas at constant volume V is shown by the straight line A. Now, mass of the gas is doubled and volume is halved then the corresponding pressure versus temperature graph will be shown by the line.
A
B
C
None of these
So at constant volume pressure versus temperature graph is a straight line passing through origin with slope . As the mass is doubled and volume is halved slope becomes four times. Therefore, pressure versus temperature graph will be shown by the line B.
