All fluids are compressible - even water. Their density will change as pressure changes. Under steady conditions, and provided that the changes in pressure are small, it is usually possible to simplify analysis of the flow by assuming it is incompressible and has constant density. Liquids are quite difficult to compress - so under most steady conditions they are treated as incompressible or "relatively incompressible." In some unsteady conditions very high pressure differences can occur and it is necessary to take these into account, even for liquids. Gases, on the contrary, are very easily compressed. It is essential in most cases to treat these as compressible, taking changes in pressure into account.
No, Liquid is not compressible. Though it will move to fit its current habitat.
No, it is a liquid.
Fluids include liquids and gasses. Liquids are not compressible. Gasses are compressible. Water is a liquid and it not compressible.
Co2
Solid and liquid states are not compressible.Solids.Solids
No, because it is not compund substance
A liquid is the type of matter which has the form of the container and is very low compressible.
Mercury, aka: "Quick Silver"
they are not compressible
Gas is the most compressible because the atoms have the most space in between. Solids are the least compressible because their atoms are tightly packed. Degree of compressibility will depend entirely on the substance in question.
