Non-covalent attractions is another term for the same thing. Vapors obey the gas laws because they are gases. Increasing temperature increases vapor pressure (charles law) Larger molecules have higher molar heats and bpts because they tend to have more imfs ex. : butane is a 4-c chain which is a gas at room temperature but 8-
