"Force the substance into a smaller volume" is pretty much the definition of "compress".

How is pressure affected when a gas is compressed?
When a gas is compressed, so volume is decreased, the pressure increases. P=1/V
What gas law describes when adding gas to a balloon will cause the volume to decrease?
The volume decrease only when the external pressure increase.
What volume of gas would be in a cylinder of 100cm3 after a week?
- if the cylinder is sealed by welding, the same volume- if the cylinder is open - any initial gas
What law of gas decrease in temperature and decrease in volume?
Charles's Law
Define compressed natural gas?
Compressed natural gas is natural gas under pressure which remains clear, odorless, and non-corrosive. This is when natural gas is compressed to less than 1% of its volume at standard atmospheric pressure.
What happens if a piston is used to decrease the volume of a contained gas?
The volume will increase as the piston moves downward. If the cylinder is sealed and the gas can not escape, the pressure in the cylinder will decrease. If the cylinder has a small opening as in a motor, the higher pressure outside will push in air that will mix with fuel to ignite when the spark plug is fired. (Supv note: it is not possible to have negative pressure. You can have zero pressure but not a deficit.)
Why does the volume of a gas decrease when pressure increases?
As pressure increases, the molecules of the gas are compressed, reducing the amount of space between molecules, which results in a decreased volume.
When Compressed Natural Gas is filled in a cylinder will the cylinder get heated up?
If the gas is compressed into the cylinder, yes. However if the gas is already pre-compressed (to the point of liquefaction) and simply decanted into the cylinder, there will be little to no heating of the receptacle cylinder.
When a pressure on a gas increases will the volume increase or decrease?
For a fixed mass of gas, the gas will become compressed by pressure and its volume will decrease. This is why pressurized gas containers explode when breached: the container breach eliminates the barrier between the gas compressed by the container and the outside air; the pressurized gas immediately increases the volume it occupies in the explosive decompression until its density equals the density of the regular atmosphere.
Can the particles in gas be compressed into smaller volume?
Yes, a gas can be easily compressed.
When a gas is compressed in a cylinder what does the distance between the gas molecules do?
The compression will result in a lowering in the average distance between molecules of the gas. Imagine that the cylinder is like that in an internal combustion engine, with a piston inside the cylinder. The compression is accomplished by pressing the gas into a reduced volume. The number of gas molecules remains the same. With the same number of molecules in a reduced volume, the gas molecules are pressed more closely together, lowering the average distance between the gas molecules.
When was the first compressed gas cylinder made?
1945
Can volume vary in an isolated system?
ya its possible now we suppose the example of adiabatic process in this process when we compressed the gas in a cylinder rapidly the volume varies and there is no transfer of energy and mass
As the temperature of a fixed volume of a gas increases the pressure will?
decrease
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).
How is pressure affected when a gas is compressed?
When a gas is compressed, so volume is decreased, the pressure increases. P=1/V
What gas law describes when adding gas to a balloon will cause the volume to decrease?
The volume decrease only when the external pressure increase.
