Chapter 13, Problem 61AE

Interpretation Introduction

Interpretation:

Energy of water absorbed by student’s hand has to be calculated.

Concept Introduction:

Heat of condensation is the quantity of heat released on condensation of a steam to liquid. Every substance has different heat of condensation. It is represented as $-{\text{ΔH}}_{\text{v}}$ and calculated as follows:

  $\text{Energy}=\left(\text{mass}\right)\left({\text{ΔH}}_{\text{v}}\right)$

Heat of fusion is quantity of heat required to convert liquid to solid. Every substance has different heat of fusion. It is represented as ${\text{ΔH}}_{\text{fus}}$ and calculated as follows:

  $\text{q}=\left(\text{mass}\right)\left({\text{ΔH}}_{\text{fus}}\right)$
