Questions & Answers

Q: Are stones transparent or opaque?

Stones are opaque, not transparent. Glasses, on the other hand, are transparent.

Q: Why does a notebook not have any shine?

Notebooks do not shine because they lack luster, unlike objects that have a shiny surface.

Q: Does chalk dissolve in water?

No, chalk powder is insoluble in water, so it does not dissolve.

Q: Why does a piece of wood float on water?

Wood floats on water because it has a lower density than water, causing it to float.

Q: Why does sugar dissolve in water?

Sugar is highly soluble in water, so it dissolves completely when mixed with water.

Q: Can oil mix with water?

No, oil does not mix with water. It remains on the top as they are immiscible.

Q: Does sand settle down in water?

Yes, sand settles down in water because it does not mix with water due to its insolubility.

Q: Does vinegar dissolve in water?

Yes, vinegar dissolves in water completely, and both substances mix well.

Summary & Key Takeaways

• Materials can be sorted into groups based on their properties, such as transparency, solubility, and shape.

• Stone is opaque, not transparent, and glasses are transparent.

• Chalk powder is insoluble in water, while sugar and vinegar are soluble.

• Wood floats on water due to its lower density, unlike oil which does not mix with water.
