(a)
Interpretation:
The difference is pressure across the liquid-air interface for a mercury droplet of radius 125 nm needs to be calculated
Concept Introduction:
Surface tension (γ) is the energy required to increase the surface area of a liquid by 1 m2
For a droplet of radius r, the surface tension across a pressure gradient ΔP is given as:
