In Mayer's relation, C P - C V = R 'R' stands for

Options

  1. Atranslational kinetic energy of 1 mol gas
  2. Brotational kinetic energy of 1 mol gas
  3. Cvibrational kinetic energy of 1 mol gas
  4. Dwork done to increase the temperature of 1 mol gas by one degree

Correct answer

D. work done to increase the temperature of 1 mol gas by one degree

Step-by-step solution

PV = RT (For 1 mol) …(i) P V + Δ V = R T + 1 …(ii) From equation (i) and (ii), P Δ V = R i.e., W = R (work done).
