Question

the molecular motion of liquid and gas in which path​

Answer 1

Answer:

They move in al directions.

Explanation:

They move in all directions because they are fluids and have the ability to flow.

Answer 2

Explanation:

Thermal Expansion: The intermolecular forces in liquids are strong enough to keep them from expanding significantly when heated (typically only a few percent over a 100°C temperature range). Thus the volumes of liquids are somewhat fixed. Notice from Table S1 (with a shorten version in Table 11.1.1 ) that the density of water, for example, changes by only about 3% over a 90-degree temperature range.

Diffusion: Molecules in liquids diffuse because they are in constant motion. A molecule in a liquid cannot move far before colliding with another molecule, however, so the mean free path in liquids is very short, and the rate of diffusion is much slower than in gases.
