A drop of water is broken into two drops, The sum of which property of the two drops is equal to that of the single one?

Correct answer: Volume

Explanation: When a drop of water breaks into two, the total volume remains constant. 📚 Other Information: ▪️ Volume is a conserved property in such transformations. ▪️ The surface area increases as one drop splits into two. ▪️ Surface energy also increases due to greater surface area. ▪️ This is why breaking a drop requires energy input. ▪️ The radius of smaller drops decreases compared to the original. ▪️ Surface tension resists the breaking of drops. ▪️ This concept explains why raindrops tend to merge rather than split. ▪️ Practical use is seen in atomisation processes (sprays and perfumes).
