Answer 2

Explanation of the Phenomenon

When a piece of soap is pressed firmly against a wet plate and then lifted, the plate will be lifted along with the soap. This phenomenon occurs due to the creation of a vacuum between the soap and the plate, which results in an adhesive force that causes the plate to stick to the soap.

Reasoning Behind the Phenomenon

The phenomenon can be explained by the principles of surface tension and the creation of a seal between the soap and the plate. When the soap is pressed against the wet plate and then lifted, a thin layer of water becomes trapped between the soap and the plate. This creates a seal, and as the soap is lifted, the seal remains intact, causing the plate to be lifted along with the soap.

Scientific Principles at Play

The key scientific principles at play in this phenomenon are surface tension and the creation of a seal due to the presence of water. Surface tension is the property of a liquid that allows it to resist an external force, and in this case, it contributes to the formation of the seal between the soap and the plate. The presence of water is crucial for the creation of the seal, as it allows for the formation of a thin layer of water that acts as the adhesive force between the soap and the plate.

Conclusion

In conclusion, the lifting of the plate along with the soap when it is pressed firmly against the wet plate and then lifted is due to the creation of a vacuum and the formation of a seal between the soap and the plate, which is facilitated by surface tension and the presence of water.
