After burning for three hours, a candle has lost half of its mass. Explain why this example does not violate the law of conservation of mass.

The law of mass conservation depicts that the mass of reactants is equal to the mass of products, so the mass of the candle is changed from **solid **state to gaseous state which have the same mass of the wasted candle.
What is the law of conversation of mass ?
According to the law of conservation of mass, it has been described that the mass neither formed nor destroyed, it can only transferred from one state to another state.
Due to changes in states of matter, the mass is only rearranged and changed, so during a chemical reaction, the mass of the reactants and the products are same in a **closed reaction. **
There for when burning the candle it only changes its** state **from solid to gaseous state that follow the law of conservation of mass.

Burning a candle does not violate the law of conservation of mass because the mass before burning equals the mass of the products after burning, which include gases that escape into the air. When wax burns, it transforms into gases and ash, but total mass remains constant. Thus, while the candle seems to lose mass, it simply changes form rather than disappearing.
