Which of the following relations does not give the equation of an adiabatic process, where terms have their usual meaning?
Options
- Ap^ 1- T^ = constant
- Bp V^ = constant
- CT V^ -1 = constant
- Dp^ T^ 1- = constant
Correct answer
D. p^ T^ 1- = constant
Step-by-step solution
For adiabatic process, p V^ = constant For an ideal gas, p V=n R T or p= n R T V Again, from ideal gas equation, aligned V &= n R T p p ( n R T p )^ &= constant p^ 1- T^ &= constant aligned Hence, relation shown in option (d) is not for adiabatic process.
