Paraffin is thermally decomposed by burning; carbon dioxide and water vapors are produced.
Paraffin wax is typically solid at room temperature.
When a candle burns, the paraffin wax reacts with oxygen to form carbon dioxide and water vapor. The carbon atoms in the paraffin combine with oxygen from the air to produce heat, light, carbon dioxide, and water. This chemical reaction is why the substances in paraffin change when a candle burns.
When paraffin burns in plenty of air, carbon dioxide and water vapor are formed
Paraffin burns because it reacts with oxygen in the air when exposed to a heat source. This reaction releases heat and light energy, causing the paraffin to combust and produce flames.
Sodium burns in water as it gets reacted with the oxygen in water and yields NaOH and that is why it is stored in Paraffin.
My physical therapist says you can reuse the paraffin in a home paraffin spa. You wouldn't want a salon or physical therapist to reuse theirs, because you wouldn't want other people's germs on your skin.

Yes
Paraffin oil is a gas at 450 oC.
When a candle is burned, the paraffin wax is heated and undergoes a chemical reaction with oxygen from the air, resulting in combustion. The paraffin wax is broken down into smaller molecules like carbon dioxide and water vapor, releasing energy in the form of heat and light. The process is a physical and chemical change.
No. A paraffin test collects physical evidence, it is not self-incriminatory.
When paraffin wax is heated, it melts and turns into a liquid state. Upon further heating, the liquid paraffin wax can begin to vaporize and produce fumes. If the temperature is too high, paraffin wax can catch fire.
