The expansion of an ideal gas of mass m ...

The expansion of an ideal gas of mass `m` at a constant pressure `P` is given by the straight line `D`. Then the expanison of the same ideal gas of mass `2m` at a pressure `P//2` is given by the straight line

A

E

B

C

C

B

D

A

Text Solution

Verified by Experts

The correct Answer is:
D
`PV=nRT=m/MRTrArrV/Tpropm/P," slope "m/P`
First condition -
`Drarr" slope "=m/P`
Second condition -
slope `=(2m)/(P//2)=4(m/P)`
i.e. slope becomes four times so graph A is correct in this condition
