1. Melting of the candle is a physical change.
2. Burning and thermal decomposition are chemical changes.
because of the digestions system of the candle is visible
Nope. A chemical change becuase of the reaction from the heat.
CHEMICAL
There are multiple physical changes and chemical changes that occur when a candle burns. One physical change is that the candle melts back into liquid wax. One chemical change is flame burning on the wick.
Burning a candle is a chemical change, as is burning anything.
Burning a candle is a chemical change. It cannot be "unburnt"
It is both a physical and chemical change. The burning of the wick s chemical while the candle melting being physical.
Physical change means change physically while chemical change means change chemically or change in chemical properties.Like if you would drop a chip of zinc in sulphuric acid it will its color will be changed which is no doubt a physical change.But,also its properties are changed as it will be transformed into zinc sulphate from simple zinc,thus it also undergoes a chemical change. Now,with your question,the candle breaks but the candle remains the candle,so,its not a chemical change but a physical change only.Hope it helps!
It is actually both. The burning of the wick involves a chemical change. The physical change is the wax.

The melting of the wax is a physical change. The burning the of wick is the chemical change
because it can
it doesn't matter how high it is, if its burning, its a chemical change
Nope. A chemical change becuase of the reaction from the heat.
