One mole of a monatomic ideal gas undergoes a cyclic process as shown in the figure (where V is the volume and T is the temperature). Which of the statements below is (are) true?

Step-by-step solution

( A ) Process- I is not isochoric, V is decreasing ( B ) Process- I I is isothermal expansion ∆ U = 0 , W > 0 ∆ Q > 0 ( C ) Process- I V is isothermal compression ∆ U = 0 , W 0 ∆ Q 0 ( D ) Process- I a n d I I I are NOT isobaric because in isobaric process T ∝ V hence isobaric T – V graph will be linear
