Question

Which of the following is true in the case of
an adiabatic process, where y = Cp/cv
​

Answer 1

Answer:

where is the following but

Answer 2

Answer:  In an adiabatic process heat supplied is zero. Hence internal energy change equals work done.

Hence, W=ΔU

−PdV=  

γ−1

nR

​  

dT=  

γ−1

PdV+VdP

​  

 

−γPdV=VdP

−γ  

V

dV

​  

=  

P

dP

​  

 

ln(P)+γln(V)=C

PV  

γ

=constant

Putting V=  

P

nRT

​  

 

P  

1−γ

T  

γ

=constant

Answer is option A.
