Question

Is burning of candle reversible and irreversible both is there any example like this also

Answer 1

Burning of candle is a reversible as well as an irreversible reaction because this process includes physical as well as chemical process. When the solid wax gets converted into vapours, its is physical & reversible change but when those vapours burn, it is chemical & irreversible change.

Answer 2

Most probably candle would come under both the reversible and irreversible because we know that we can let wax change again after it changes into other state that is into the gaseous state. But if the same wax will instead of just changing it's state into the gaseous state it goes under more over heat it would burn and because of this the burning of candle is irreversible.
