Why does flame burn with a conical flame?

Answer 1

When a flame burns, hot gases are produced and these combine with the air to generate heat. Flames get their tongue-like or tear-drop shapes due to the movement of these gases that are influenced by the gravity of the Earth.

Answer 2

When a candle starts burning, the wick catches fire first. Wax burns because wick burns. Wick burns because wax burns. The wick transfers the heat to its lower part and the wax around the wick, near the bottom, melts. This creates hemispherical liquid wax which rises through the wick by capillary action (Surface tension). Wick is like a bunch of capillary tubes. The wax on the wick burns using the oxygen from surrounding air. The air molecules gain energy and their excitation and de-excitation produce heat and light. The heated air around the burning wick becomes lighter and due to buoyant force, it rises upwards (Buoyancy). It is like a hot ball of gas immersed in relatively cooler air. The

upward moving air gets accelerated and its velocity increases (Acceleration). Thus the

pressure along the path of moving air drops (Bernoulli's theorm). The surrounding air

squeezes in since its pressure is more. The velocity of the hot air moving up is largest at

the top (because it is accelerated) and thus the pressure drop is largest there. So the

surrounding air squeezes in at the top much more than at the centre of the flame. Thus

the pointed top of the flame and the wider flame at the bottom is explained. At the very

bottom, the flame again narrows down. This, by common sense, is explained as- The wax in the wick burns at a point from where the flame disperse outward and consequently is wider than the source of burning.

Answer 3

Because of the energy, the chemicals cause in the flame.

becuzzz it just iz....2012 graduate

Answer 5

well for one thing it always changes...
