What happens when a candle is Burning?

When a candle starts to burn thermal energy is created. A chemical reaction is occurring as the candle melts.

The candle is heating up which causes the atoms to change phases leaving it in a solid and liquid state. The atoms begin to start shifting for vibrating to moving more freely.

Chemical reaction for wax burning.

A chemical reaction called combustion is occuring, the wax reacts to oxygen in the air to make carbon dioxide.

An unlit candle contains potential chemical energy because the candle has the potential to release energy but will not until it is lit by fire.

A lit candle contains kinetic radiant and thermal energy. It contains thermal because the temperature increased, It contains radiant because you can feel the heat if you touch it.

Close up of candle burning

pbrister19 — 2017-11-06 00:32:12 UTC

Labeled with the fire(thermal/radiant), the brunt wick, the wax in it's solid/liquid state rolling down the sides.

Before

pbrister19 — 2017-11-06 00:52:29 UTC

E(th) - 2 is represent nothing is really happening there yet
E(ph)- 1 box to represent solid
E(ch)- 5 to show it's chemical energy
E(radiant)- 2 to show no radiant yet

After

pbrister19 — 2017-11-06 01:21:23 UTC

E(th)- The fire made the amount of thermal energy rise because there was more of it
E(ph)- 2 representing that it was in both a solid and liquid
E(ch) - there was no more
E(radiant)- Now that there was a flame lit there is more radiant energy ( like light or when u hold your hands up close cupped around the candle)

pbrister19 — 2017-11-06 01:21:23 UTC

Both add up to 10

pbrister19 — 2017-11-06 01:38:14 UTC

This is because energy is neither lost nor create.
