Q. Four curves $A,B,C$ and $D$ are drawn in the adjoining figure for a given amount of gas. The curves which represent adiabatic and isothermal changes are
A) $C$ and $D$ respectively
B) $D$ and $C$ respectively
C) $A$ and $B$ respectively
D) $B$ and $A$ respectively
Explanation
(c) As we know that slope of isothermal and adiabatic curves are always negative and slope of adiabatic curve is always greater than that of isothermal curve
Hence in the given graph curve $A$ and $B$ represents adiabatic and isothermal changes respectively
