Which of the following relations does not give the equation of an adiabatic process, where terms have their usual meaning?

Options

  1. Ap^ 1- T^ = constant
  2. Bp V^ = constant
  3. CT V^ -1 = constant
  4. 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.
