Answer 2

Dear friend, as we all know when our light in house goes off at night , we all are in just darkness. But when you take a candle and burn it , you got the light.
If we think what happens in this process , this is how it
goes on :--

1. when candle burns , it releases carbons as a smoke.(if you notice)

2. a slimy substance gets on the floor, which is solid in nature.

3. it is a chemical change , because it releases carbons as smoke during burning.

4. it is also a physical change , because when the wax is melt , after certain time , it gets back into a solid.


Just that much. Not so much rocket science.
