Why is the ember of a cigarette harder than the non-burning tobacco alone?

  1. Jun 8, 2012 #1
    The glowing end of a lit cigarette appears to be more solid/sturdy/hard than the loose tobacco that makes it up.
    This may be more of a chemistry question, but why is this?

    I'm not sure about the exact scientific explanation, but essentially that part has lost its moisture and is in the process of becoming primarily carbon. That alters the chemical bonds.
