1.	Critical temperature for carbon dioxide and methane are 31.1^@C and - 81.9^@Crespectively. Which of these has stronger intermolecular forces and why?
Answer» Solution :Higher the critical TEMPERATURE, more easily the GAS can be LIQUEFIED. This is possible only when intermolecular FORCES are stronger. THUS, `CO_2` has stronger intermolecular forces than `CH_4`.
