प्रश्न
A plastic cube is released into the water. Will it sink or come to the surface of the water?

उत्तर
- When dropped into water, the plastic cube floats on the top rather than sinking. The term "buoyancy phenomenon" refers to this.
- When compared to other objects, plastic has a high rate of buoyancy and is water-repellent. Plastic naturally floats on the water's surface because it is lighter than water.
- The same experiment will result in a glass cube sinking because it weighs more than the liquid it is released into.
