1.	Two gases A and B have critical temperatures as 250 K and 125 K respectively. Whione of these can be liquefied easily and why?
Answer» <p>Gas A with the critical temperature 250K can be liquefied easily.</p><p>Explanation:</p><p>Liquefaction of gases takes place when the intermolecular force between the molecules becomes so strong that the gas molecules come together to attain liquid state. Liquefaction can be attained by cooling the gas so that the kinetic energy of the molecules reduces and they slow down. Therefore, a higher critical temperature is easier to attain as we start cooling the gas.</p>
