Chapter 3, Problem 82E

Interpretation Introduction

Interpretation: The final temperature attained by a sample of water of mass $45\text{kg}$ on absorbing $345\text{kJ}$ of heat at an initial temperature of $22.1°\text{C}$ is to be calculated.

Concept Introduction: The relationship between heat and change in temperature used to determine the amount of heat absorbed is

$q=mC\Delta T$

Here, $q$ is the amount of heat, $m$ is the mass of the substance, $C$ is the specific heat capacity, and $\Delta T$ is the change in temperature.
