Surface energy of a soap bubble
Did you know?
WebA soap bubble is an extraordinarily beautiful thing and yet it requires virtually no skill to produce. This is because surface tension does all the work for you, making sure that a perfect spherical liquid membrane is produced every time. In fact it is impossible to blow imperfect bubbles. WebImportantly, the contribution of the surface energy is given by E s = 2 γ A, where γ is the surface tension and A is the surface area of the bubble. The factor of 2 emerges, since there are actually two interfaces (one facing …

WebHence, the surface energy per unit area of a surface is numerically equal to the surface tension. EXAMPLE 7.10. Let 2 .4 × 10 − 4 J of work is done to increase the area of a film of soap bubble from 50 cm2 to 100 cm 2. Calculate the value of surface tension of soap solution. Solution: nth term meaning for kidsWebConsider a free-body diagram for a half-sphere of a particle (or soap bubble) as shown above: radius is r, and circumference (at equator) is 2п r. ∆P is the internal pressure relative to the outside pressure. γ is surface energy.
