    Kettles and pots are heated from below to maximize the heat generated from fire, because, hot temperature comes up while cold temperatures goes down.

    If the fire was position upside, it can generate heat for kettle but it will require and use much more energy as compare when the kettles and pots are heated from below.

    Heat rises, thats why ovens are hotter at the top as well. By heating water from the bottom you waste less heat.

    light a match and hold your hand 30cm above the flame (not too close), you will feel the heat. Now light another match and hold it 10 cm (for safety) beneath it and you wont feel the heat at all smile

    * If you turned a pot or kettle upside down, the lids would open up and everything would fall out.

    * If you tried turning a gas cooker upside down and turning it on, you will find that the flames tend to go "upwards"

    * If you had the pressure "high" enough (example a blow torch) then you could cook a pot or kettle from "above"

    Because water conducts heat badly, and heat can be distributed through it quickly only by making the lighter hot water rise through the colder water above it.

    If a piece of ice be fixed at the bottom of a tumbler and covered with cold water it is possible to boil the water at the surface without melting the ice.
