Question

Wax is heated in a china dish .how will the following changes during heating ? (a) kinetic energy of particles (b) inter particles distance

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.

Answer 2

a)when the particles are heated then the temperature will rise and when the temperature will rise the kinetic energy will also be rise.b)as a temperature rise and kinetic energy also rise then the particle move away from each other and interparticle distance increases.
