Chapter 12.2, Problem 21PP

To determine

Heat of fusion and vaporization for the given figure.

Answer to Problem 21PP

The heat of vaporization is $Q_f=334000\text{J/kg}$ and heat of vaporization is $Q_v=2259300\text{J/kg}$ .

Explanation of Solution

Given:

The given diagram is,

  

Calculation:

Latent heat of fusion: It is the requiredheat, to change the state from solid to liquid at the same temperature.

For the above figure, the heat of fusion is

  $\begin{array}{l}{Q}_f=395700-61700\\ =334000\text{J/kg}\end{array}$

Latent heat of vaporization: It is the required heat, to change the state from liquid to vaporat the same temperature.

For the above figure, the heat of vaporization is

  $\begin{array}{l}{Q}_v=3073000-813700\\ =2259300\text{J/kg}\end{array}$

Conclusion:

Therefore, the heat of vaporization is $Q_f=334000\text{J/kg}$ and heat of vaporization is $Q_v=2259300\text{J/kg}$ .
