QUESTION 1 (a) Determine the gage pressure inside a 2-mm-diameter soap bubble in atmospheric air. The surface tension of the soap solution at 20 °C is 0.025 N/m. (b) The figures below represent FBDS of cross-sections of a water droplet and soap bubble. Assume that they have the same diameter and thickness of the soap bubble is negligible, which of them has a higher surface tension? Why?
