The burning sensation in your muscles when you have depleted oxygen is often due to the buildup of lactic acid, a byproduct of anaerobic metabolism. This buildup can irritate nerve endings in the muscles, leading to the sensation of burning. Stretching and increasing blood flow can help alleviate this feeling.
A burning candle goes off when covered by a glass cup because it uses up the available oxygen in the cup, creating a sealed environment with no oxygen for the flame to continue burning. This causes the flame to extinguish due to the lack of oxygen needed for combustion.
When you cover the top of a glass with a burning candle inside, you restrict the flow of oxygen to the flame. This causes the flame to consume the available oxygen within the glass, leading to the extinguishing of the flame due to lack of oxygen. Additionally, the heat and gases produced by the burning candle may build up within the glass.
Chillies contain a compound called capsaicin, which binds to receptors in the mouth that are normally activated by heat. This sends a signal to the brain that the mouth is experiencing a burning sensation, even though no actual heat is present.
Candle wax evaporates when the candle is burning because the heat from the flame causes the wax to melt and turn into a gas, which then evaporates into the air.
Burning chocolate is a chemical change because the heat causes the chemical structure of the chocolate to change, leading to the release of new compounds and altering the composition of the chocolate.
