Chapter 6, Problem 6.82QP

Interpretation Introduction

Interpretation:

The molar heat of Vaporization of Liquid Nitrogen has to be calculated.

Concept Introduction:

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.

$\text{q=cmΔT}$

Where,

$\text{q=}$ Heat added

c= Specific heat

$\text{m=}$ Mass

$\text{ΔT=}$ Change in temperature.

The unit of specific heat is $\text{J}{\text{g}}^{\text{-1}}\text{.°C}$ .

To calculate: The molar heat of vaporization of Liquid Nitrogen
