Chapter 22, Problem 22.11E

Interpretation Introduction

Interpretation:

The change in pressure on coalscence of two $\text{1}\text{.00-nm}$-radius water droplets at $20.0°\text{C}$ into a single droplet is to be calculated.

Concept introduction:

Surface tension is the tension of a liquid surface that causes due to the attraction of liquid particles in the liquid surface by the liquid particle present in the bulk of the liquid. The surface tension tries to attain a minimum surface area. The formula of surface tension is given by the expression as shown below.

$\gamma =\frac{w}{\Delta A}$
