Pressure versus temperature graph of an ideal gas at constant volume V is shown by the straight line A. Now mass of the has is doubled and the volume is halved, then the corresponding pressure versus temperature graph will be shown by the line

Options

A. A
B. B
C. C
D. None of these

Answer

B

Explanation

`PV=m/MxxRTrArrP=(mRT)/(MV)`
At V = constant, P vs T graph is a straight line
slope `=(mR)/(MV)`
(slope). `=(2mR)/(MV//2)=4((mR)/(mV))`
