Hypothesis: That is really up to you; it is what you think based on your past experience and observations of matter. It could be that liquids and gasses are compressible and that solids are not.
Observations: Only the air (a gas ) is compressible. The other 2 forms of matter do not compress. Also, that when you stopped applying pressure to the air in the syringe that the plunger came back up.
Conclusion: The only form of matter that is compressible was the gas (air). This must mean that there are spaces between the molecules. These spaces are made smaller when the pressure of the plunger is applied.
Also, because the plunger comes back up when you release the pressure with the gas this must mean that the molecules of gas have alot of energy and therefore speed. The energy of the gas particles hitting the plunger pushes back on the plunger and it goes back to its original position.
