A student places a small amount of water in a glass dish and then carefully places a small paperclip on the surface of the water. The paperclip floats. What happens if the student adds a drop or two of dish soap to the water? Check all that apply. The paperclip falls through the water to the bottom of the dish. The soap acts as a surfactant. The soap increases the surface tension of the water. The soap decreases the surface tension of the water.

When soap is added then the paper clip will fall as soap is a surfactant and decreases the surface pressure. The surface strain of water holds the paper.

What is the mechanism of floatation?

The paper clip is lighter in weight and floats on the water surface as the density and mass play a major role in floatation. Any addition of substances like soap will lead the clip to fall or sink.

The addition of the soap lessens the pressure of the water surface as it is a surfactant and will affect the surface strain of water.

Therefore, when soap is added, paper clips will fall.
