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.
What is the melting candle wax that is dripping down the side of the candle an example?
Physical change.
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.
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.
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?
There are 2; the melting of the candles wax is physical but the wick burning is chemical.
What is the melting point of candle?
The melting point of the candle is 47 Celsius.
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.
What is a chemical reaction melting ice rubbing a marker on paper burning a candle rusting iron?
Rusting iron is the chemical change.
Is a candle an example of sublimation?
A candle is an example of melting and burning.
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.
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.
What is the melting candle wax that is dripping down the side of the candle an example?
Physical change.
Is ice melting chemical reaction?
ice melting is a physical reaction

Is candle wax a physical property?
Candle wax are generally organic compounds. melting of candle wax is a physical property
