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.
Sound will travel fastest through a solid because the molecules in a solid are closer together, allowing for faster transmission of sound waves. Liquids and gases have molecules that are more spread out, hindering the speed at which sound can travel through them.
heterogeneous
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.
Light travels faster through liquid than through solid. The speed of light in a medium is determined by the refractive index of the material, which is lower in liquid compared to solid materials.
it is so compact it can not spread out like a liquid
Yes through condensation it becomes a liquid, and through deposition it becomes a solid.
The word you are looking for is "dissolved." When a solid substance breaks down into individual molecules and is evenly spread out in a liquid, we say that it has dissolved in the liquid.
Generally speaking no. Some people say that glass is a liquid- that one always comes up as it has no real solid to liquid transition point. The argument is that if you leave it long enough it will spread, so it's a liquid. Its debatable though.
liquid
That depends on the liquid and the solid. Liquid mercury has a very high density. Liquid gasoline has a very low density. At the melting point the density of a liquid and a solid are almost the same.
