Chapter 9, Problem 7ALQ

Interpretation Introduction

Interpretation:

When water in an open beaker evaporates over time the change in its vapor pressure has to be illustrated.

Concept introduction:

The phenomenon of evaporation of liquid is transition from “liquid phase” to “vapo r phase”. Almost all the liquids have the tendency to evaporate either spontaneously at room temperature without the effect of “external energy” or in the presence of external energy like heat etc.

Vapor pressure of the liquid is defined as the pressure of its vapor state that exists in equilibrium with the liquid state.
