Viscosity of the liquid
A gas cannot easily pass through a liquid or a solid however it can be entrapped in it . If a gas bubble is formed in a liquid it moves upward and escapes out of the liquid. Gas cannot pass through a solid barrier.
Solid, liquid, or gas.
The material through which a wave moves is called the medium. It can be solid, liquid, or gas, and the properties of the medium affect how the wave behaves and travels.

Sound moves through a solid faster than anything. In order it goes, solid, liquid, and gas. So metal is faster than water is faster than air.
It is because it moves and solids are hard.

Generally, sound moves faster through a solid than through a liquid. This is because the molecules of a solid are more condensed than those of a liquid. However, sound does not move faster through all solids than through all liquids.1
A solid is changed to liquid form of matter through melting A liquid changed to a solid is freezing
Filtration is a technique that uses a porous barrier, typically a filter paper or sieve, to separate a solid from a liquid. The liquid passes through the barrier while the solid particles are retained on the filter.
