1. A.
   $\int_{268\text{ }K}^{333\text{ }K} C_{p}dT + \frac{\Delta H_{\text{melting~}}}{273} + \frac{\Delta H_{\text{boiling~}}}{373}$
2. B.
   $\int_{268\text{ }K}^{273\text{ }K} \frac{C_{p,m}}{T}dT + \frac{\Delta H_{m},\text{~fusion~}}{T_{f}} + \frac{\Delta H_{m,\text{~vaporisation~}}}{T_{b}}$

   $$+ \int_{273\text{ }K}^{373\text{ }K} \frac{C_{p,\text{ }m}dT}{\text{ }T} + \int_{373\text{ }K}^{383\text{ }K} \frac{C_{p,\text{ }m}dT}{\text{ }T}$$
