Critical temperature is the temperature above which the gas cannot be liquefied, how so ever high pressure we may apply.

Higher the critical temperature, more easily the gas can be liquefied, i.e., stronger are the intermolecular forces. Hence, CO2 has stronger intermolecular forces than CH4

Listen properly First see the no of which you are going to find log and check how many digits are before decimal if there are 2 digits before decimal put 1. Before your answer now forget about decimal see 1st 2 no under the 3rd no and write it after that 1. And if there is one more no. After that see again in mean difference and add it to previous one.
