(i) As the temperature rises, particles move ……………..

(ii) With increase in temperature, the kinetic energy of the particles also ………… .


(iii) The rate of diffusion of liquids is ………… than that of solids.

i. faster


Particles of matter are continuously moving and as we increase the temperature, particles move faster. Their speed increases to a great extent.


ii. increases


Particles of matter are continuously moving that is, they possess what we call the kinetic energy. As the temperature increases, kinetic energy of the particles also increases.


iii. higher


The rate of diffusion of liquids is higher than that of liquids because in the liquid state, the particles move freely. There is so much space between each other. In solids, the particles are packed tightly and cannot move freely.
