One mole of an ideal gas is carried through the reversible cyclic process as shown in figure. The max. temperature attained by the gas duing the cycle
A
`(7)/(6R)`
B
`(12)/(49R)`
C
`(49)/(12R)`
D
None of these
Text Solution
Verified by Experts
The correct Answer is:
C
Max. temp. attained by gas in between B to C According to equation of straight line `(P-4)/(1-4)=(V-1)/(2-1)` `rArr" "P-4=-3V+3` `rArr" "P=7-3V` For 1 mole gas `(RT)/(V)=7-3V,RT=7V-3V^(2)` …..(1) `R(dT)/(dV)=7-6V=0` `V=(7)/(6)` put in Eq. (1) `RT=(7-3xx(7)/(6))xx(7)/(6)` `rArr" "T=(49)/(12 R)`
