Vedclass · Answer

(A) In a standard Carnot cycle represented on a $P-V$ diagram:$1$. The process $A B$ represents an isothermal expansion at a higher temperature $T_1$.$2$. The process $B C$ represents an adiabatic expansion.$3$. The process $C D$ represents an isothermal compression at a lower temperature $T_2$.$4$. The process $D A$ represents an adiabatic compression.Therefore,the portion $A B$ represents the isothermal expansion.

The Carnot cycle is plotted on a $P-V$ graph. Which portion represents an isothermal expansion?
