Question

If a candle is burnt, the chemical energy is transformed into ___________.

Answer 1

Hint: When a candle is burnt, we can see the light coming from the flame, and of course, the flame must be at least red hot. The burning is a chemical reaction and thus energy transformations take place.

Complete step by step solution:
All of us have seen a burning candle. What we are directly seeing would be the flame on the thread on the top of the candle. We all know that burning is a chemical reaction. Whenever a chemical reaction happens, there exists a transformation or formation of new particles along with an energy transmission or energy transformation.

When we consider the burning of the candle as a chemical reaction, here also chemical reaction and energy transformation takes place. Some gases and other particles or molecules are produced and transform their states.
We are discussing the energy transformations happening while the burning of a candle. When we lighten a candle with a flame, the heat of the flame melts the wax. This melted wax is absorbed by the thread and thus further burns the candle till the thread burns out.
The candle is a chemical substance which is holding chemical energy as it is capable of burning. This chemical energy is the cause of production of light and heat from a burning candle.

That is the chemical energy within the candle spread out into its surrounding in the form of thermal energy and light energy.

Note: Candles are made generally from the paraffin wax, which is a byproduct of refining petroleum products. They can also be made from microcrystalline wax, beeswax (from the nest of honey bees), gel (a mixture of mineral oil and polymer), or some plant waxes (generally carnauba, bayberry, palm or soybean wax).
