What do you need To change a gas to a liquid you need to lower the?

To change a gas to a liquid, you need to lower the temperature and/or increase the pressure. Cooling the gas reduces its kinetic energy, allowing molecules to come closer together and form a liquid. Alternatively, increasing the pressure compresses the gas, forcing the molecules closer together, which can also lead to condensation into a liquid. Both methods are essential in processes like liquefaction of gases.
