The P-V diagram of a diatomic ideal gas system going under cyclic process as shown in figure. The work done during an adiabatic process CD is (use γ=1.4) :

  1. –500 J
  2. –400 J
  3. 400 J
  4. 200 J

Solution

Adiabatic process is from C to D
WD=P2 V2-P1 V11-γ
=PDVD-PCVC1-γ
=200(3)-(100)(4)1-1.4
=-500 J
