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!
A melting candle is an example of a physical change, not a chemical reaction. The process involves a solid candle turning into liquid wax due to the application of heat, with no change in the chemical composition of the wax molecules.
The melting of the wax is a physical change. The burning the of wick is the chemical change
Burning a candle is a chemical change because the wax undergoes a chemical reaction with oxygen in the air to form new substances like carbon dioxide and water. This process results in the candle getting shorter as it burns.
does lghtning a candle chage its appearance?
It is a chemical change.
The melting of a candle is a physical change because it is a change in state from solid to liquid without altering the chemical composition of the candle.
A burning candle involves both physical and chemical changes. The physical change is the melting of the wax, while the chemical change is the wax combining with oxygen in the air to produce heat, light, carbon dioxide, and water vapor.

The melting of a candle is a physical change. It involves a change in state from solid to liquid due to the absorption of heat energy, without any change in the chemical composition of the candle wax.
It is a chemical change; burning (combustion) is a chemical process.
The hardening of candle wax is a physical change. This is because the wax simply changes from a liquid to a solid state without any change in its chemical composition.
Lightning is a physical change. It results from the movement of charged particles in the atmosphere, causing a visible electrical discharge. This process does not involve any change in the composition of the substances involved, making it a physical 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.
Yes, candle wax melting is a physical property because it involves a change in the state of matter from solid to liquid without altering the chemical composition of the wax.
When a candle is burnt a physical AND chemical change takes place. Its a physical change when the wax is being melted because the chemical structure has not change, meaning it cannot be a chemical change. Its also a chemical change because you are burning the string. When you burn something the chemical structure DOES change, meaning it is a chemical change.
