Answer:
The force of surface tension supports the metal bin on the surface but when soap solution is added, the surface tension reduces so the metal bin sinks.
Explanation:
- The characteristics of the surface of the water that enables it to defy any force from the outside because of the united characteristics of the water is called surface tension.
- This is seen because it is one of the property of the molecule to attract each other and is liable for many other properties of the liquid.
- Adding soap to the water results in the surface tension of the water being low and makes the molecules of the water stick together.
