Science experiments and tests are always carried out using specific conditions and parameters. These can be pressure, temperature, volume or the close surrounding around us which determines a 'tentative' results. The environment or the surrounding in which the tests are run plays a very important role and it has large affect on the result of the experiment. Thus these scientific experiment are carried at controlled conditions to obtain the desired results.
Convention is known as one of the driving forces of atmospheric circulation. Convection is defined as the heat transfer due to bulk movement of the molecules within fluids like liquids and gases, uncluding th molten rock. Convention takes place through diffusion, advection or can be both and it is usually a domination form of heat that transfer into liquids and gases.
