P-V Diagrams & Cyclic Processes

An ideal gas has undergone through the cyclic process as shown in the figure. Work done by the gas in the entire cycle is ________ ×10−1 J\times 10^{-1}\text{ J}. (Take π=3.14\pi = 3.14)

Answer: 314

  1. Work in the cycle = area of the circle on the V-P graph.
  2. Radius along P: 100100 kPa =105= 10^{5} Pa; radius along V: 100100 cm3=10−4^3 = 10^{-4} m3^3.
  3. W=π×105×10−4=10π=31.4W = \pi \times 10^{5} \times 10^{-4} = 10\pi = 31.4 J =314×10−1= 314 \times 10^{-1} J
  4. Answer: 314.
