Chapter 13, Problem 13.42SP

Interpretation Introduction

Interpretation:

The sign of ${\text{ΔH}}_{\text{sol}}$ needs to be determined and the change in temperature when solute is dissolved in the given enthalpy changes needs to be explained.

Concept introduction:

The sum of internal energy and the product of volume and pressure of the system is known as enthalpy of the system. It is the thermodynamic property of the system. The specific enthalpy is denoted by $\text{h}$, and general enthalpy by $\text{H}$. The unit of enthalpy is joule, calorie and used British thermal unit.
