Question

Why do different liquids possess different boiling point

Answer 1

Explanation:

Different liquids have different boiling points depending on the strength of bonding between the particles and the mass of the particles. The heavier the particles in the liquid, and the stronger the bonding, the higher the boiling point will be.

Answer 2

Answer:

Let us take 2 common liquids:

(i) water; and (ii) diethyl ether....
