Originally Answered: Why a burning candle has shape like a pear (talking about fire)? Actually the shape should be that of a sphere, because light and heat is radiated outwards, but because of heat, the air becomes light and less denser, due to which it rises up, and hence we get that shape.
How would you describe a candle?
A candle is an ignitable wick embedded in wax, or another flammable solid substance such as tallow, that provides light, and in some cases, a fragrance. A candle can also provide heat or a method of keeping time.
What is the structure of a candle?
Candle wax is a mixture of solid carbon compounds called hydrocarbons. When a candle is lighted, the wax melts, rises up the wick and gets converted into vapour. These wax vapours burn in the air producing a yellow, luminous flame.
