Why is a candle melting a marshmallow a chemical change?
Because the chemical composition is modified.
Is burning a candle a chemical change or a physical change give reason?
It is both a physical and chemical change. The burning of the wick s chemical while the candle melting being physical.
Is candle burning physical change?
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!
What part of a burning candle takes place and physical change?
The melting of the wax is a physical change. The burning the of wick is the chemical change
Is candle wax melting exothermic?
no because when a substance changes its state of matter then it is NOT considered a chemical reaction or a chemical change.
Is candle wax melting physical property?
Melting candle wax is a chemical change. Why? Because when you cook or burn candle wax it melts so it is a chemical change.
Is melting wax physical property?
Melting candle wax is a chemical change. Why? Because when you cook or burn candle wax it melts so it is a chemical change.
Why is a candle melting a marshmallow a chemical change?
Because the chemical composition is modified.
How is a burning candle both physical and chemical changes?
because of the digestions system of the candle is visible
Is a candle melting a physical change or a chemical change?
It is a physical change because when it melts it is still a candle just a melted one
What are the steps to prove that a burning of a candle is physical as well as a chemical change?
1. Melting of the candle is a physical change. 2. Burning and thermal decomposition are chemical changes.
Is candle wax melting chemical or physical change?
It is a physical change, from a solid to a liquid. The chemical composition of the wax remains unchanged.
Is burning a candle a chemical change or a physical change give reason?
It is both a physical and chemical change. The burning of the wick s chemical while the candle melting being physical.

Why is melting of covered candle a physical change while burning of a candle wick a chemical change?
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.
Why burning of candle is a physical and chemical change?
CHEMICAL
What part of a burning candle takes place and physical change?
The melting of the wax is a physical change. The burning the of wick is the chemical change
