Chapter 3, Problem 94E

Interpretation Introduction

Interpretation: The final temperature of ethanol that absorbs $562\text{J}$ of heat at a temperature of $11°\text{C}$ is to be calculated.

Concept Introduction:

Density is defined as mass per unit volume.

$d=\frac{m}{V}$

Here, $m$ is the mass of the substance and $V$ is the volume of the substance.

When a substance absorbs heat $q$, the temperature change for this substance is directely proportional to the heat absorbed and expressed as follows:

$q=mC\Delta T$

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