Chapter 4, Problem 26QRT

Interpretation Introduction

Interpretation:

From the two given substances, the one that requires greater thermal energy transfer to warm from 25${}^{\text{o}}\text{C}$ to100${}^{\text{o}}\text{C}$ has to be identified.

Concept Introduction:

Energy: It is the capacity or ability to do work. Joule (J) is the SI unit of energy.

Specific heat:

Specific heat can be defined as quantity of heat required to raise the temperature of $\text{1}\text{g}$ substance by $\text{1°C}$. The relationship between heat and change in temperature can be expressed by the equation given below.

    $\text{q}=\text{cmΔT}$

Where $\text{q=}$ Heat added

    c= Specific heat

  $\text{m=}$ Mass

  $\text{ΔT=}$ Change in temperature.
