Question

Describe an experiment to demonstrate surface tension using a soap.

Answer 1

Answer:

In this experiment, the dish soap again acts to decrease the surface tension. Because we decrease the surface tension near one end of the stick, the water molecules will actually move from low to high.

Answer 2

Explanation:

1.Fill the plate with a thin layer of water. Less than an inch deep is enough.

2.Sprinkle pepper onto the water. Try to cover as much the surface as possible. (The more pepper, the more spectacular the effect!)

3 Dip your finger into the liquid soap.

4.Say “Abacadaba” and touch the pepper in the water.
