Chapter 5, Problem 36QP

Interpretation Introduction

Interpretation:

The heat liberated by a mercury metal in the given system is to be calculated.

Concept Introduction:

Heat absorbed or released by a system is calculated by multiplying the mass of the substance with its specific heat and the change in temperature of the system.

Sign of heat change is positive, if heat is absorbed by the system, and negative, if heat is released by the system.

The heat liberated by the substance in the given system is calculated by the expression as follows:

$q=ms\left(T_2-T_1\right)$

Here, $q$ is the heat change, $m$ is the mass of mercury, $s$ is the specific heat capacity of mercury, $T_1$ is the initial temperature, and $T_2$ is the final temperature of the system.

The conversion of heat from $\text{J}$ into $\text{kJ}$ is done as follows:

$1\text{J}={10}^{-3}\text{kJ}$
