When the temperature reaches a specific point, called the condensation point, the gas transitions into a liquid. This is because:
* The attractive forces between the particles become strong enough to overcome the kinetic energy of the particles. This means they are no longer moving freely, but rather are held close together in a more ordered arrangement.
* The gas molecules lose enough energy to change their state of matter.
Essentially, cooling a gas reduces the kinetic energy of its particles, allowing the intermolecular forces to take over and form a liquid state.
