Question

If we burn a candle what changes is occur around us?

Answer 1

Both Physical and Chemical changes occur.
Upon heating, the wax first undergoes the process of melting followed by heating. Here, melting is a physical change as the melted wax can again be obtained as solid wax upon the removal of heat, whereas, burning is a chemical change, as once the wax has been burnt, it cannot be obtained back in its original form.
