this is because both work done and heat transfer cycle should rotate either clockwise or anticlockwise. This is available in only first option.In options there is no option for choosing fig.3,4 .

  5. .The following four figures have been drawn to represent a fictitious thermodynamic cycle, on the P-V and T-S planes. According to the first law of thermodynamics, eqcal areas are ehicitseay thermodynamics. (A) Fig 1 and 2 (B) Fig 1 and 3 (3) Fig 1 and 4 (4) Fig 2 and 3


  6. fig- 1 fig. 2 fig- 3 fig.4 What is the area under p-v diagram?Work transfer What is the area under T-s diagram? = Heat transfer According the First law of thermodynamics in a cycle, we have We see that figure 1 and 2 satisfies the first law of thermodynamics and hence both have the same area.
