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.

Answer:

It doesn’t violate the law of conservation of mass the because the mass that is lost is just converted to melted wax and smoke that is produced. If you record the mass of the smoke and the melted wax, you will surely end up with the mass of the original candle.
