Question

C1 and C2 represent the specific heat of a liquid and its saturated vapour where- as L is latent heat of vaporization. (T is the temperature) The correct option is

• A. $C_2-C_1=\frac{dL}{dT}-\frac{L}{T}$
• B. $C_1-C_2=\frac{dL}{dT}+\frac{L}{T}$
• C. $C_1+C_2=\frac{dL}{dT}-\frac{L}{T}$
• D. $C_1+C_2=\frac{dL}{dT}+\frac{L}{T}$
