Answer 1

Hey mate !!

Here's your answer !!

The candle burning gives rise to both physical and chemical change. The explanation is given below.

Physical change:

While burning takes place the size or the height of the candle gradually decreases due to melting of wax. This is called the physical change as no new products are formed.

Chemical change:

While burning the candle takes oxygen for combustion. Here the oxygen is converted as fuel which then turns the spark and heat into fire. Hence new product is formed. Due to this it is called as chemical change.
