Which of the statement is correct?

A

Slope of adiabatic `P-V` curve will be the same as that of isothermal one.

B

Slope of adiabatic `P-V` curve is smalller than that of isothermal one.

C

Slope of adiabatic `P-V` curve is larger than that in isothermal one.

D

Slope of adiabatic `P-V` curve may be smaller or larger depending on the value `V` .

Text Solution

Verified by Experts

The correct Answer is:
D

Slope of `PV` curve, for isothermal process `(dP)/(dV)=-(P)/(V)`
Slope of `PV` curve, for adiabatic process `(dP)/(dV)=-gamma(P)/(V)`
As `gammagt1((dp)/(dV))_("adiabatic")gt((dP)/(dV))_("isothernal")`
