Gas Cylinder
The pressure
inside the container is so high that the gas particles are compressed
very closely together. This liquefies the gas inside the cylinder. When
the valve is opened, the higher pressure in the cylinder (compared to the air pressure outside the cylinder) forces the particles
of the liquefied gas out through the hose into the surroundings (with
lower pressure in comparison). Due to the change in pressure, the particles now take the form of
gaseous state.
Silinder Gas
Tekanan gas
dalam bekas adalah amat tinggi. Zarah-zarah gas dimampatkan sehingga
rapat. Hasilnya, gas dalam silinder mengambil bentuk cecair. Apabila
injap silinder dibuka, tekanan
gas
yang lebih tinggi di dalam bekas memaksa zarah-zarah gas keluar
melalui hos ke persekitaran (secara bandingan mempunyai tekanan gas
yang lebih rendah). Disebabkan perubahan tekanan
ini, zarah-zarah bertukar bentuk kepada gas.
