EFFECT OF CHANGE OF PRESSURE :-
👉 The process of conversion of gas into liquid by increasing pressure and decreasing temprature is called liquefaction of gases.
👉 On applying pressure, the intermolecular space in gases decreases and the molecules come closer.
👉 On reducing pressure the reverse process takes place.
👉 Solid carbon dioxide is also called dry ice is converted directly to carbon dioxide gas by decreasee in pressure upto 1 atm withot coming into liquid state.
👉 The pressure exerted by a gas is measured in atmosphere.Atmospheric pressure at sea level is taken as 1 atmosphere which is also normal atmospheric pressure.
