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. BPV = constant
  3. CT W⁻¹= constant
  4. DP^ T^ 1- = constant

Correct answer

D. P^ T^ 1- = constant

Step-by-step solution

Adiabatic process Heat does not exchange between system surrounding and eq. is PV ^ = constant Ideal gas P V=n R TP= n R T V = n R T V ~V ^ = const TV ^ -1 = constant Again P V=n R TV= n R T P Pulley in eq. (i) P ( n R T P )^ = constant P^ 1- T ^ = constant...(iii) So, option (d) does not give the relation.
