Melting doesn't change the composition of a compound (substance).
Burning is a chemical reaction, an oxidation - new compounds are formed.
What else can I help you with?
What is wax susceptible?
It is susceptible to heat -- it will melt.
Is a wax burning a reversible change?
No, burning wax is an irreversible change. When wax is burned, it undergoes a chemical reaction that changes it into different substances (carbon dioxide, water vapor, and heat) that cannot be easily reversed.
Why does the wax not freeze at the top of candle?
The wax at the top of a candle does not freeze because as the wax near the wick is melted and burned, it creates a pool of liquid wax that acts as a fuel source to keep the flame burning. The heat from the flame also helps to melt any solid wax near the top of the candle, preventing it from freezing.
Why does a white candle melt faster than a colored candle?
White candles typically melt faster than colored candles because they are made from a purer wax, such as paraffin or soy wax, which has a lower melting point. Colored candles often contain additional dyes and additives that can raise the melting point and slow down the burning process.
Lower the melting point of wax?
To lower the melting point of wax, you can consider adding a small amount of mineral oil or vegetable oil to the wax before melting it. This will decrease the overall melting temperature of the wax. Alternatively, you can mix the wax with a lower melting point wax to create a blend with a reduced melting point.
What is the difference between melting and burning wax?
Melting is a change of state from solid to liquid. Burning is reacting a substance with oxygen, otherwise known as combustion.
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 a wick necesarry in a burning candle?
Yes that is what burns the melting wax prolongs the burning time by slowly evaporating
What is wax susceptible?
It is susceptible to heat -- it will melt.
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
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 soy wax burn faster than paraffin wax?
Soy wax burns slower than paraffin wax because it has a lower melting point and a cooler burning temperature. This means that soy wax candles typically have a longer burn time compared to paraffin wax candles.
Is candle wax burning an exaple of an physical change?
Only the melting is physical (can easily be reversed by cooling down) but the actual burning (flame) is a complicated chemical set of reactions.
Is a wax burning a reversible change?
No, burning wax is an irreversible change. When wax is burned, it undergoes a chemical reaction that changes it into different substances (carbon dioxide, water vapor, and heat) that cannot be easily reversed.
Why does wax melt in boiling water?
Wax has a lower melting point than boiling water, so when placed in boiling water, the heat from the water causes the wax to melt. The molecules in the wax absorb the heat energy from the water, which ultimately leads to the wax melting.
Why does the wax not freeze at the top of candle?
The wax at the top of a candle does not freeze because as the wax near the wick is melted and burned, it creates a pool of liquid wax that acts as a fuel source to keep the flame burning.
