5. Why does the smell of a burning incense stick spreads throughout the room?
6. Explain why the solubility of a solute in a particular solvent increases on heating?

Answer 1

Answer:

5. The smell of a burning incense stick spreads throughout the room at the molecules of gases have very high inter - molecular spaces and occupies the entire space available to it.

6. The solubility of a solute in a particular solvent increases as :

a.) The molecules of the solvent start turning into their gaseous form and their inter - molecular spaces increase.

b.) The molecules of the solute heat up, get excited and start vigorous to and fro motion in their positions. This facilitates mixing of the solute in the given solvent.
