How does burning candle affect mass differently than melting a candle?

Yes, mass of a burning candle is decreasing because caron dioxide gas is escaping and cannot be weighted on a normal balance. Molten candle fat has the same weight as solid 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.

Is it a physical change when a candle changes size by burning?
Yes, because the candle wax isn't actually burning, just melting
Why is a candle melting a chemical change?
Melting is accompanied by burning and thermal degradation - two chemical reactions.
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.
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
A melting candle demonstrates which reaction?
A melting candle demonstrates physical reaction.
Is a candle an example of sublimation?
A candle is an example of melting and burning.
What name is given to a process such as a burning a candle?
melting and burning
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 it a physical change when a candle changes size by burning?
Yes, because the candle wax isn't actually burning, just melting
Why is a candle melting a chemical change?

How is a burning candle both physical and chemical changes?
because of the digestions system of the candle is visible
Is a wick necesarry in a burning candle?
Yes that is what burns the melting wax prolongs the burning time by slowly evaporating
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.
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.
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.
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
Does a candle holder effect burn rate?
yes the candle holder effects the candle burning, because it will hold the candle back from melting faster. i perfer not using one...and it'll be a variable
