Gas Liquefaction Explained: High Pressure Effect
Liquefaction is the process where a gas changes into a liquid.
How Pressure Causes Gas Liquefaction
Gases naturally have molecules that are far apart.
Applying high pressure forces these molecules closer together. This action significantly reduces the space between particles.
As the distance between molecules decreases, the intermolecular attractive forces become more significant.
When these attractive forces overcome the molecules' kinetic energy, the gas undergoes a phase change and liquefies.
Key Takeaway
The primary reason gases liquefy under high pressure is the reduction in intermolecular space, enabling attractive forces to dominate.
