Chapter 10.7, Problem 10.49QAP

Interpretation Introduction

(a)

Interpretation:

The total amount of heat needs to be calculated for the given system.

Concept Introduction:

The amount of heat involved in a process without changing the phase can be calculated as follows:

  $q=m\left(\text{g}\right)\times \text{C}\left({\text{J/g }}^{\circ }\text{C}\right)\times \Delta \text{T}\left({}^{\circ }\text{C}\right)$

Here;

q is heat in J, m is mass of the substance in grams, C is specific heat in J/g °C and $\Delta \text{T}$ is change in temperature in ${}^{\circ }\text{C}$ .

If the phase is changing at certain temperature, the heat can be calculated as follows:

  $q=\text{mass }\left(\text{g}\right)\times \Delta H\left(\text{J/g}\right)$

Here, ∆H = Enthalpy change due to change in phase.
