Question

when wax is heated in a conical flask that has a long glass tube attached to it the vapour of wax? ​

Answer 1

Wax is heated in a china dish .

Then effect on:

(a) kinetic energy of particles:

According to kinetic theory of matter,

Matter is composed of small particles which move continuously.

As temperature is a measure of average kinetic energy of particles.

As wax is heated, particles gain heat energy and kinetic energy of particles increases.

(b) inter particles distance:

As wax is heated , particles gain heat energy and thus increase internal energy of system and particles overcome the force of attraction. And changes the state to liquid.
