Heat travels oppossite direction of gravity

    if see a candle light you find the flame moving up.heat moves by conduction, convection
    ans radiation. a teapot with water boils. this are the few example which make us think.

    That is not the transfer of heat. That is the movement of a fluid. (Gas and liquids are both fluids) Hot air is less dense than cooler air, so the hot air rises. The same is true of liquids.
    This can, and usually does result in the transfer of heat from one area to another, but heat is not solely traveling in one direction as you might imagine it to be.

    i think we can test the truth of how heat flow is effected by temperature gradient, gravity, electro-magnetic field to clear our thoughts and perceive the truth. the three iron rod forming x - axis, y - axis, z - axis should be heated on earth and in space station and readings recorded to check how heat spreads. and this structure of rods has to heated in vaccum.i think that would be interesting. this experiment will help us understand how really heat energy flow is effected by gravity. similarly a similar structure should be placed in neutral space in between two north poles of a magnet also to quench our thirst for knowledge.

    Heat transfer is a thoroughly understood science. There is no need for such an experiment.
