Questions  

On an isothermal process, there are two points A and B at which pressures and volumes are (2P0, V0) and (P0, 2V0) respectively. If A and B are connected by a straight line. find the pressure at a point on this straight line at which temperature is maximum:

a
4P03
b
54P0
c
32P0
d
75P0

detailed solution

Correct option is C

P=−P0V0V+3P0PV=−P0V0V2+3P0V ………(i)T=1nR−P0V0V2+3P0V ………(ii)For Tmax,dTdV=0+3P0−2P0VV0=0  or  V=32V0  ………(iii)From Eq. (i), P=+32P0
