Chapter 22, Problem 22.22E
Interpretation Introduction

Interpretation:

The pressure difference in a droplet of liquid helium is to be determined.

Concept introduction:

Laplace-Young equation is a fundamental equation for the behavior of an interface. This equation relates the pressure difference on either side of an interface with the surface tension and the area of the liquid changes with volume. The Laplace-Young equation in terms of radius and surface tension is shown as below.
