Answer 1

Answer:

Explanation:

Because of that, the pepper can't dissolve in the water. ... As the soap moves into the water, and the surface tension changes, the pepper no longer floats on top. But the water molecules still want to keep the surface tension going, so they pull back away from the soap, and carry the pepper along with them.

Answer 2

EXPERIMENT

Black pepper and soap experiment

Aim- To demonstrate soap effects the surface of water.

Materials used- Container, water, dish soap,pepper, toothpick pencil, paper.

Procedure-

• At first, fill the container with an inch of water.

• Sprinkle pepper evenly across the surface in a way that it should float upon the surface of water.

• Squeeze a tiny bubble of dish soap onto a clean plane. Touch the tip of of the toothpick to take a little amount of soap on it.

• Make that soapy toothpick's end touch the surface of water. You'll observe pepper darted to the sides of the pan.

Result-

• Most of the pepper flakes will have darted to the sides of the container.

• Also, some of the flakes would have fallen to the bottom of the container.

• It may have looked like the soap was scrambling the pepper flakes away.
