Oxygen and flame.
it burns and makes more fire
it's a candle from the wax it makes the fire heat up
A fire makes a crackling sound when it burns.
the wick Burns but it produces heat that melts the wax
the product is when parafin wax combines with oxygen.
Some wax burns, and as it does so, chemical changes occurs. Wax converts to CO2, CO, and H2O. That is an exothermic reaction The rest of the wax melts with the increased temperature. That is the physical change.
Hair needs to be away from the wax. Sleeves need to be enclosed so that wax doesn't get into your sleeves. Safety goggles need to be close by if the wax gets above 60 degrees. In summary, protect yourself from burns or from getting something you are wearing in the wax or near the heat source that melts wax. And protect your eyes. Always.
When wax burns, energy is released in the form of heat and light. This is due to the combustion of the hydrocarbons in the wax, producing carbon dioxide and water vapor along with the energy.
Oxygen.
Yes, fire can make noise when it burns. The crackling and popping sounds are caused by the rapid expansion of air and moisture in the fuel as it heats up and releases gases.
use of wax for burning out side the body or inside the body
When a candle burns, the heat melts the wax, which then becomes liquid and flows down the sides of the candle. This process is called wax pooling. The liquid wax provides fuel for the flame to continue burning.
