Chapter 15, Problem 15.65P

Interpretation Introduction

Interpretation:

The amount of heat that can be removed by $1\text{ ton}$ air conditioner has to be calculated.

Concept Introduction:

Molar enthalpy for a process is heat energy needed by $\text{1}\text{mol}$ of a substance to undergo change in the process. Heat energy absorbed by $\text{n}\text{mol}$ of substance toundergo change is as follows:

  $q=n\left(\Delta H\right)$

Here,

$q$ is heat energy in $\text{kJ}$

$n$ is moles of substance.

$\Delta H$ is enthalpy for process in $\text{kJ/mol}$ .

The value of $\Delta H$ is positive always as energy needed to overcome interactions between the liquid molecules.
