Chapter 7, Problem 49E

Interpretation Introduction

Interpretation: The temperature change of given substance and absorbed heat should be determined.

Concept Introduction: The heat capacity C is defined as the ratio of heat absorbed to the temperature change. It can be given by,

$\text{C = heat absorbed/ temperature change}$

• Require heat for one gram of substance raise to its temperature by one degree Celsius is called specific heat capacity.

$\text{Specific heat capacity = Absorbed heat }\left(\text{J}\right)\text{/ Temperature change}\left(\text{c}\right)\times \text{mass ofsubstance }\left(\text{g}\right)\mathrm{...}\left(\text{1}\right)$

From the above equation heat is:

$\text{q = S×M×T}\mathrm{....}\left(2\right)$

                                                        q is heat (J)

                                                       M is mass of sample (g)

                                                       S is specific heat capacity $\left(\text{J/°C·g}\text{.}\right)$

                                                       T is temperature change (C)
