Chapter 15, Problem 61A

Interpretation Introduction

Interpretation:

The process by which amount of energy required to raise the temperature of an object is to be determined.

Concept introduction:

Specific heat of the object is helpful to calculate amount of energy required to raise the temperature of an object.

As,

Specific heat is defined as quantity of heat required to raise the temperature of one gram substance by one degree Celsius.

Answer to Problem 61A

The quantity of energy required can be calculated by using formula:

$\begin{array}{l}q=mc\Delta T\\ whereqisquantityofenergyabsorbed\\ m=givenmass\\ \Delta T=riseintemperature\\ cisspecificheat\end{array}$

Explanation of Solution

By knowing the amount of substance, change in temperature and specific heat of the substance, we can calculate the energy required to raise the temperature using the following formula:

$\begin{array}{l}q=mc\Delta T\\ whereqisquantityofheatabsorbed\\ m=givenmass\\ \Delta T=riseintemperature\\ cisspecificheat\end{array}$
