How does the kinetic-molecular theory explain the following properties of liquids:

(a) relatively high density,
(b) ability to diffuse, and
(c) ability to evaporate?

Respuesta :

Answer:

"Kinetic energy of the gas is more as compared to that of the liquids. But when compare it to the solid, kinetic energy of liquid is more."

Explanation:

a) Relatively high density : This happens as a result of the tight or packed or can be say close arrangement of the particles.

b) Ability to diffuse : As we know that in gases the constant and the random motion of the particles of the liquid leads to diffusion. But it is very slow as compared to the gases and also porque liquid particles are close together.

c) Ability to evaporate:This happens as a result of the molecules of the liquid having different kinetic energies with particles having higher than that of the average energies that move faster.

The kinetic energy of gases is higher than that of liquids. However, as compared to solids, liquids have higher kinetic energy.

Kinetic energy and density:

a) Relatively high density: This occurs as a result of the particles being tightly packed or near together.

b) Diffusion ability: We know that in gases, diffusion is caused by the continual and random motion of the liquid particles. However, it is exceedingly sluggish compared to gases, and because liquid particles are close together, it is also quite slow.

c) Evaporation ability: This occurs as a result of the liquid molecules having variable kinetic energies, with particles having higher than average energies moving quicker.
