Nitrous oxide,hydrocarbons and greenhouse

    greenhouse and increase in number of gas molecules in atmosphere

    How much atmospheric heating is due just to the fact that as the number of gas molecules increases (through human activity) the temperature of a fixed volume rises?

    No one knows (i dare to say). Im not sure that increasing # of molecules alone will automatically increase temperature in real atmosphere,ie, cannot treat it as fixed volume.

    Probably none! the number of gas molecules in the atmosphere is more-or-less the same with or without human activity, and also the atmosphere cannot be treated as a fixed volume.

    Gravity limits how much the atmosphere can expand so there would be a limit to how much the volume could change.

    how does that happen?

    You are right - it wouldn't.
