Well it is simple when you think about it reallly. The wax melting from the heat of the flame is the physical change. It will turn turn into a liquid and then later solidify.
There are 2; the melting of the candles wax is physical but the wick burning is chemical.
No.
Burning coal is a chemical reaction, a chemical change; but the solid reactant is transformed in gaseous products (H2O and CO2) - this is a physical change.
a physical change can be reversed a chemical one can'tA chemical change is when a new substance, with new and different properties, is produced. The identity of the original substance is changed. In contrast, a physical change is when one or more of a substance's physical properties have simply been altered; no new substance is produced.
the physical change is -the shape of the candle changes,some of the wax becomes liquid to solid. chemical change-the wick is burned *Hi just wanted to say that this person above is wrong...I mean, the wick burning would be a chemical change because it is combustion. They are wrong because the wick doesn't actually burn.The wax is absorbed by the wick which cools it off. Eventually the wick becomes too long and the top of it dries out and falls off into the wax. Fact being, the wax vapor burns. You should do some more individual research for details because there is more. Thanks!
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.
It is actually both. The burning of the wick involves a chemical change. The physical change is the wax.
1. Melting of the candle is a physical change. 2. Burning and thermal decomposition are chemical changes.
The melting of the wax is a physical change. The burning the of wick is the chemical change
burning of candle
because of the digestions system of the candle is visible
Yes, because the candle wax isn't actually burning, just melting
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!
because it can
This is because a candle will change its whole form and stay that way, which is a physical outer change. And a candle wick only burns, it doesn't change it's appearance.
The wax melts, it can solidify into a solid again.
