Chapter 3, Problem 102E

Interpretation Introduction

Interpretation: The amount of heat energy required for heating the air in the room from $7°\text{C}$ to $28°\text{C}$ is to be calculated from the relationship between heat absorbed and change in temperature.

Concept introduction:

When a substance absorbs heat $q$, the temperature change for this substance is directly proportional to the heat absorbed and is 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.
