Option B: The pressure inside the soap bubble is less than atmospheric pressure. This is due to the surface tension of the soap film. Surface tension causes the soap bubble to minimize its surface area, resulting in a slightly higher pressure inside the bubble compared to outside. However, this pressure is still less than atmospheric pressure. The soap film acts like a stretched elastic membrane, exerting an inward force that balances the tendency of the bubble to expand due to the pressure difference. If the pressure inside the bubble were greater than atmospheric pressure, the bubble would burst. Therefore, option B is correct. Options A, C, and D are incorrect as they do not accurately describe the pressure inside a soap bubble. It’s crucial to understand the role of surface tension in maintaining the shape and stability of soap bubbles, as it influences the pressure distribution inside the bubble.
