What Does Condensation Do
Indeed, producing liquid gasses by human beings is also carried out using the compression and condensation of gasses, which is according to the same principle that is done in nature. When liquid air or liquid gas is released from pressure, it turns into a gas and scatters throughout the air.
So now we have realized that a very ethereal gas that did not have any material form has transformed into a tangible and visible liquid, and then transformed back into its rather invisible gas state.
