When the weather is hot, will there be solid objects when the candle is lit and burned out?

The wax oil of candles will solidify when the temperature exceeds 30 degrees. Because wax oil must reach more than 50 degrees to melt. It solidifies automatically before it reaches 50 degrees.

1. The main components of candles are carbon and oxygen compounds, which react with oxygen in the air when burning to generate water and carbon dioxide.

2. When observing the whole process of candle burning, scientists found that the mass of water and carbon dioxide produced by candle burning is exactly equal to the sum of the mass of candle and the mass of oxygen consumed by candle burning. In other words, the substance that makes up the candle has not disappeared, but has become something else. In fact, all substances in the world are like this. Things change endlessly from one thing to another, but their total mass is equal before and after the change.
