Question

A cyclic process of an ideal monoatomic gas is shown in figure. The correct statement is (are):

• A. $W_{AB}>W_{BC}$
• B. Net heat energy has been supplied to the system
• C. Temperature of the gas is maximum in state B
• D. In CA, heat is rejected by the system

Answer 1

The correct option is B Net heat energy has been supplied to the system

Let $T_A=T\Rightarrow T_B=T$
$BC\to P_{constant},V\propto T,V_{increases}\Rightarrow T_{increases}$
$T_c>T_B=T_A=T$
Area under BC > Area under AB.
CA $\to$ temperature decreases + $\Delta$ W = O (isothermal)
$\Delta Q$ must be given out of the system.
