Chapter 5, Problem 43QP

Interpretation Introduction

Interpretation:

The metal which takes longer time to increase its temperature, out of the given metals, A and B, under the given conditions, is to be predicted.

Concept Introduction:

The amount of heat absorbed by a given mass of substance depends upon the specific heat capacity of the substance. Higher is the specific heat capacity, higher is the heat required to raise the temperature of substance, and lesser is the absorption of heat by the substance.

The specific heat (s) of a substance is the amount of heat required to raise the temperature of 1 g of the substance by $1°\text{C}$.

The heat absorbed by a substance in the given system is calculated by the formula,

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

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