Surface tension soap film formula
WebMeasure 6 cups of water into your container, then pour 1 cup of dish soap into the water. Slowly stir until the soap is mixed in, being careful to not let foam or bubbles form. Measure 1 tablespoon of glycerin or 1/4 cup of corn syrup and add it to your container. Stir the solution until it is well mixed. WebFind the surface tension in the soap film. Data: Radius of soap bubble (r) = 25 mm = 0.025 m D p = 2 Bar = 2 x 10 5 N/m 2 Formula: Pressure inside a soap bubble and surface tension ( s) are related by, D p = 4 s /r Calculations: s = D pr/4 = 2 x 10 5 x 0.025/4 = 1250 N/m Water has a surface tension of 0.4 N/m.

Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water striders) to float on a water surface without becoming even partly submerged.
