Chapter 7, Problem 52E

Interpretation Introduction

Interpretation:

The specific heat capacity and the molar heat capacity of mercury are to be calculated.

Concept Introduction:

The heat capacity C is defined as

C = heat absorbed/ temperature change

• The heat capacity of one gram of substance is called as a specific heat capacity.

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

• The heat capacity of one mole of substance is called as a Molar heat capacity.

$\text{Molar heat capacity =Absorbed heat }\left(\text{J}\right)\text{/ Temperature change}\left(\text{c}\right)\text{×mole}\mathrm{....}\left(\text{2}\right)$

• Mole is the ratio of  weight of substance and molecular weight (g)

$\text{Mole = weight of substance }\left(\text{g}\right)\text{/molecular weight }\left(\text{g}\right)\mathrm{....}\left(\text{3}\right)$
