Chapter 9, Problem 9.ACP

Interpretation Introduction

Interpretation:

Four enthalpy changes whose sum would equal to the difference in the vaporization of water at ${100}^{\circ }C$ and at ${25}^{\circ }C$ have to be listed.

Concept Introduction:

If a transition or process is taking place where the initial and final state of the substance are different, then the formula for calculating the heat required for the process is given below.

  $q=ms\Delta t$

Where, $m$ is mass of the substance, $s$ is the specific heat capacity of the substance and $\Delta t$ is the temperature difference.
