When the particles are cooled, the particles condense.
<h3>What happens when a gas is cooled?</h3>
We know that the temperature is defined as the average kinetic energy of the molecules of a gas. Given that we have gases that are at a particular temperature, the average kinetic energy of the gas is in sync with the temperature of the gas.
As we cool the gas, the average kinetic energy of the gas molecules would reduce and the gases move more slowly thus they are able to come closer together. This process is called condensation of the gas.
