Four curves `A, B, C` and `D` are drawn in Fig. for a given amount of gas. The curves which represent adabatic and isothermal changes

Options

A. `C` and `D`, respectively
B. `D` and` C`, respectively
C. `A` and `B`, respectively
D. `B` and `A`, respectively

Answer

C

Explanation

c. As we know that slopesof isothermal and adiabatic curves are always negative and slopes of adiabatic curve is always greater than of isothermal curve, in the given graph curves `A` and `B` represent adiabatic and isothermal changes, resspectively.
