Q1: Due to decrease of diameter of the droplet, inside pressure intensityA
increases
B
decreases
C
remains unaffected
D
None of these.
ANS:A - increases When the diameter of a droplet decreases, the inside pressure intensity generally increases. This phenomenon can be understood through the Laplace pressure equation, which describes the relationship between surface tension, pressure difference, and curvature of a droplet or bubble. The Laplace pressure (Pl) can be expressed as: PL=2γ/r Where:
