Ice at $-5^{\circ} C$ is heated to become vapor with a temperature of $110^{\circ} C$ at atmospheric pressure. The entropy change associated with this process can be obtained from:

  • A
    $\int_{268 \ K}^{383 \ K} C_{p} \ dT + \frac{\Delta H_{\text{melting}}}{273} + \frac{\Delta H_{\text{boiling}}}{373}$
  • B
    $\int_{268 \ K}^{273 \ K} \frac{C_{p,m}}{T} \ dT + \frac{\Delta H_{m, \text{fusion}}}{273 \ K} + \int_{273 \ K}^{373 \ K} \frac{C_{p,m}}{T} \ dT + \frac{\Delta H_{m, \text{vaporisation}}}{373 \ K} + \int_{373 \ K}^{383 \ K} \frac{C_{p,m}}{T} \ dT$
  • C
    $\int_{268 \ K}^{383 \ K} C_{p} \ dT + \frac{q_{rev}}{T}$
  • D
    $\int_{268 \ K}^{273 \ K} C_{p,m} \ dT + \frac{\Delta H_{m, \text{fusion}}}{T_{f}} + \frac{\Delta H_{m, \text{vaporisation}}}{T_{b}} + \int_{273 \ K}^{373 \ K} C_{p,m} \ dT + \int_{373 \ K}^{383 \ K} C_{p,m} \ dT$
