Pressure inside an ideal soap bubble
Description
The pressure inside an ideal (one surface) soap bubble can be derived from thermodynamic free energy considerations. At constant temperature and in equilibrium, when the pressure inside the bubble is equal to the pressure outside of the bubble, is related to surface tension and the radius of the bubble
