11th Class Exercise 10.20

Bubble Pressure Simulation

Visualizing excess pressure in soap bubbles and air bubbles in soap solution

Bubble Radius (mm):

Value: 5.0 mm

Surface Tension (×10⁻² N/m):

Value: 2.5 ×10⁻² N/m

Depth in Solution (cm):

Value: 40 cm

Solution Density (×10³ kg/m³):

Value: 1.2 ×10³ kg/m³

Excess pressure in soap bubble: P = 4S/r = Pa

Pressure inside air bubble at depth: P = P₀ + ρgh + 2S/r = Pa

Atmospheric pressure (P₀) = 1.01 × 10⁵ Pa
