Non compressed gas has the gas particles spread out more. But when compressed packed more tightly therefore taking up less room but yet still has the same amount of atoms. So you still have the same weight but just that the particles are packed more tightly.

What happens to the number of molecules of the gas when it is compressed?
It does not change, unless a chemical reaction in the gas happens.
Is compressed natural gas a liquid?
no it's a gas, compressed to around 1% of normal volume. If it was compressed to the liquid state, you'd call it liquified natural gas (LNG).
Why does gas have no specific volume?
gas has no specific volume because the molecules can be compressed or expanded, which would change the volume. like there is a smaller volume of gas in a can of soda then in the atmesphere around you.
What term best describes a gas under greater than atmospheric pressure?
compressed gas
Why is butane gas a liquid in lighter but a gas in water?
The liquid butane in a lighter was compressed, and is under pressure. At normal temperatures, if released from the lighter it will change back to a gas. Extremely rapid evaporation.
Does the vloume of a gas change when its compressed?
Yes, when a gas is compressed it could form into a solid or liquid substance.
Which gas can be compressed and expanded?
An ideal gas can be both compressed and expanded. In regards to ideal gas, when the gas is expanded or compressed, the molecules will remain the same. In order for the count of molecules to change, gas would need to be added. The molecule count can also change if gas escapes.
What kind of substance can be compressed into a jar to change its volume?
A gas.
What happens to the number of molecules of the gas when it is compressed?
It does not change, unless a chemical reaction in the gas happens.
What weighs more an empty cylender or an cylender filled with compressed gas?
Your cylinder full of gas will weigh more, for it contains the mass of the gas. Some gases, when compressed, such as CO2, are in liquid form, and quite heavy.
Why does density increase when a gas is compressed?
There will be the same amount of gas but in a smaller space. Density is mass/volume So as volume decreases and mass is constant, the density increases.
Does a fluid's density change when it is compressed and attenuated?
Yes it does change because its mass does not change but its volume does. When it is compressed the density will increase because its volume does. When it is attenuated will decrease because the volume does. Density is mass over volume. Remember: it only works because its mass stays the same and the volume changes.
Which gas is called compressed natural gas?
CNG is compressed natural gas
Why can the vulume of a gas change and the solid of a remain constaant?
In a solid,particles are packed tightly to each other while the gas particles are not packed tightly. So the gas particles can be compressed and can change the volume. Solids cannot be compressed to change the volume.
Does a hot gas have ore mass than the some gas when it is cold?
No. Heat doesn't change the mass of a gas.
Which can be compressed more easily gas or liquid?
gas can be compressed easier.
What process solid change to gas?
Heating a solid enough will change it to gas. Or putting it in a less compressed area at the same tempterature. Or a combination of both.
