Question

Account for the following: a) particle motion increases with the rise in temperature. b) solids do not exhibit diffusion whereas gases do.​

Answer 1

Answer:

At low temperatures, most substances are solid; as the temperature increases, they ... of a substance; it does not go into changing the temperature of a substance. ... temperature, the particles in a liquid have enough energy to become a gas. ... a gas is called boiling (or vapourization), while the process of a gas becoming a ...

Explanation:

Answer 2

Answer:
a) as the temperature increases the kinetic energy present in the
Substance gets heated up due to which the kinetic energy power increases and thus vibration causes which lead to particles motion
b) Solids do not exhibit diffusion because they do not have much intermolecular spaces compared to gases to exhibit diffusion as in gases there is larger intermolecular space than solid.
