Chapter 10, Problem 10.32QP

Interpretation Introduction

Interpretation:

The heat liberated by the given metal mercury has to be calculated in kilojoules under the given conditions.

Concept Introduction:

Specific heat can be defined as quantity of heat required to raise the temperature of $\text{1}\text{g}$ substance by $\text{1°C}$. The relationship between heat and change in temperature can be expressed by the equation given below.

$\begin{array}{l}\text{Q=smΔT}\\ \text{where,}\\ \text{Q}\text{=}\text{heat added}\\ \text{c = specific heat}\\ \text{m = mass}\\ \text{ΔT= change in }\text{temperature}\end{array}$

The unit of specific heat is $\text{J}{\text{g}}^{\text{-1}}\text{.°C}$ .
