For an adiabatic process, choose the correct relation
Options
- APT^ = constant
- BP^ 1- T^ = constant
- CP^ T^ = constant
- DP^ T^ 1- = constant
Correct answer
B. P^ 1- T^ = constant
Step-by-step solution
For an adiabatic process, the relation between pressure and volume is given by: PV^ = constant From the ideal gas equation, we have PV = nRT , which gives V = nRT P . Substituting the value of V in the adiabatic equation, we get: P ( nRT P )^ = constant Since nR is a constant, this simplifies to: P^ 1- T^ = constant Answer: P^ 1- T^ = constant
