Question

State true or false and explain. Melting of wax is a physical change while burning of wax is a chemical change​

Answer 1

Answer:

It's because melted wax can be formed again in a candle but burnt is useless. Your answer is true

Explanation:

The main phenomenon responsible is the property of wax (or paraffin). Melting wax can be reshaped as a candle but once it burns it just gives out smoke and energy and thus becomes useless and also we know that melting is a physical change and burning is a chemical change. So this is the reason behind the melting of wax being physical change and burning of wax a chemical change.
