Gases are compressible because their molecules bounce off of each other instead of sticking together. The molecules of solids and liquids stick together instead of moving freely.
Solids and liquids are difficult compress. Gases, however, are easy; they respond to changes in temperature and volume.
The molecules of solid are already intact that you cannot compress them any further unless there are spaces left.
To compress gases in order to create a controlled expansion of gases thus allowing the piston to descend
The intermolecular forces in gases are weak.
Fluids can be either liquids or gases. Gas is easy to compress and expands to fill its container while liquid is hard to compress.
Gases are easy to compress because they have particles that are far apart and have weak forces between them. When pressure is applied, the gas particles can be pushed closer together, reducing their volume. This is why gases are more compressible compared to liquids and solids, which have particles that are already close together.
They make everything hotter
Materials that are rigid and lack flexibility, such as solid objects like rocks or metals, are difficult to compress or force into a smaller space. Additionally, substances that are tightly packed, like dense gases or liquids, can also be challenging to compress.
It will compress. Gases have particles that move away from each other, so if you compress it hard enough, it will push back quickly and surprisingly.
Helium can be compressed under high pressure and low temperatures to turn it into a liquid. However, it cannot be compressed to the same extent as other gases due to its unique properties as a noble gas with very low boiling and freezing points.
A pump can be used to a certain extent, but due to the compressibility of gases they are not very effective.
It is mainly hydraulic action- when water and air get into crack but as gases don't compress it burst out bringing rock with it
