How does burning candle affect mass differently than melting a candle?
When a candle burns, it undergoes a chemical reaction called combustion, where the wax reacts with oxygen to produce carbon dioxide and water vapor. During this process, the candle's mass decreases as some of the wax is converted into gases. On the other hand, when a candle melts, it transitions from solid to liquid state, but its mass remains unchanged as no chemical reaction occurs.
As a candle burns it gets shorter and shorter describe a chemical change that explain this?
I believe there is no chemical equation for this. this is because though the wick burning has a chemical reaction, the wax melting, making the candle shorter, is not undergoing a chemical reaction. simply a short change of state. If you were referring to the wick brurning though, this would be a combustion reaction. hope that helps.
Does candle loss mass when melting down?
No, a candle does not lose mass when melting down. The wax that is melted simply changes from a solid to a liquid state, but the total mass of the candle remains the same.
What is the melting candle wax that is dripping down the side of the candle an example?
The melting candle wax dripping down the side of the candle is an example of a physical change. This occurs when the solid wax is heated and transitions into a liquid state due to the heat from the flame.
Why is a candle melting a chemical change?
Melting is accompanied by burning and thermal degradation - two chemical reactions.
What type of reaction occurs when a candle is burned?
The burning of a candle is a chemical reaction called combustion, which involves the candle wax (a hydrocarbon) reacting with oxygen in the air to produce carbon dioxide, water vapor, and heat. This reaction releases energy in the form of light and heat.
Does color affect a candles melting?
No, the color of a candle does not affect its melting point. The melting point of a candle is determined by the type and quality of wax used, not by its color.
Is a candle melting a reversible change or irreversible change?
The melting of a candle is a reversible change because the solid wax can be cooled and solidified again to form a new candle.
What is the melting point of candle?
The melting point of the candle is 47 Celsius.
What is the difference between melting of candle wax and burning of candle?
Burning a candle is the process in which the wick is burnt. The wax is there to make the wick burn slower in order to let the candle burn for longer. Melting wax is part of the process but not burning the candle itself.
Is candle melting physical or chemical?
Physical.
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.
Is ice melting chemical reaction?
ice melting is a physical reaction
Is a candle melting chemical or physical?
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.

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 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
