They are packed into a smaller and smaller volume. Thus they become more dense and the pressure of the container that they are in rises.
PV = nRT
It is possible to compress gas enough to make a liquid. A propane tank has liquid in it but when it is released it is a gas. That is why it is called CNG (Compressed Natural Gas)
When compressing a gas, you are giving it less of a volume. The volume decreases, the pressure of the gas will increase.
The volume is halved
volume increases
volume increases
According to Avogadro's Law, the number of moles is proportional to the volume. Therefore, if the number of moles of gas decreases, the volume also decreases.
It changes shape and volume.
A gas. It has no definite volume or shape.
The volume is halved
the volume doubles
the volume doubles
Volume decrease.
the volume doubles

the volume doubles
The volume increases Source:
The volume increases.
The volume decreases, in accordance to Boyle's Gas Law.
The volume is doubled.
