Q: The shape of a soap bubble is spherical because:
Solution: A soap bubble adopts a spherical shape because it minimizes the surface area for a given volume, which is energetically favorable due to surface tension.
Steps: 4
Step 1: Understand that a soap bubble is filled with air and surrounded by a thin layer of soap and water.
Step 2: Recognize that the surface of the bubble is under tension, which means it tries to pull itself into the shape that has the least surface area.
Step 3: Learn that among all possible shapes, a sphere has the smallest surface area for a given volume.
Step 4: Conclude that because a sphere minimizes surface area, the soap bubble naturally takes on a spherical shape to be energetically favorable.
