WHEN IT MELTS...
It melts! It goes all soggy and droopy and liquid-ish and then disappears...
To a secret place...
Nobody knows where...
Or do we? xD :L
Yes, the density of wax decreases when heat is applied. This is because heating wax causes the molecules to move further apart, increasing the volume while the mass remains constant. This results in a decrease in density.
was: no, it doesn't change.
Now: Yes it does. Density = mass/volume. As it changes to solid, it shrinks, but the mass hasn't changed. Therefore, the density increases.
yes, wax gets less dense.
To melt wax, heat must be applied, typically from a heat source like a stove or a candle warmer. This extra heat causes the wax to reach its melting point, which is usually around 120-180 degrees Fahrenheit.
Candle wax has a low melting point, which is typically around 140-150 degrees Fahrenheit. When heat is applied to the candle, the wax melts and turns into a liquid state. This allows the wick to absorb the melted wax and fuel the flame, creating light and heat.
Wax melts in a fire because it has a low melting point. When exposed to heat, the wax undergoes a phase change from solid to liquid form. Once melted, the wax can then be used to produce light and heat.
The rate at which the candles burn is dependent on the density of the wax, not the color. Denser wax burns slower because the wax molecules are closely packed, so they do not get excited by the heat as easily.
The temperature of wax remains constant during solidification because the heat energy released as the wax cools down is used to break the intermolecular bonds in the solidifying wax, rather than increase its temperature. This energy is known as the latent heat of fusion and allows the wax molecules to form a solid structure without a change in temperature.
You can, but you need a mould, and heat.
This is a physical change, not a chemical change! It is because all the wax is still all there as for if it was a chemical change it would be all gone!Physical. Its physical state changed from solid to liquid. It's chemical make up remains the same.Melting wax is a chemical change because a new substance is forming. Trust me im intelligent and we just learned this in science.physical change :)It is a chemical change because it gives off heat even when it is burning. heat is one of the signs that tell whether it is physical or chemical change. The signs are heat , light's ,gas,discolor.Melting was would be a physical change-- no chemical reaction occurs when something melts or boils. A burning candle is a chemical change, both can occur at the same time.

'heat up' the wax!!
The density of candle wax can vary depending on the type and composition of the wax, but it typically ranges from about 0.8 to 1.0 grams per cubic centimeter. The density of the wax will also change depending on its temperature, as wax expands when heated and contracts when cooled.
Wax paper does not absorb heat. Wax paper is coated with paraffin, which does not allow heat to be absorbed. This allows wax paper to be used when cooking.

Wax paper because it has wax in it and if something has wax in it, it attracks to heat and eventually forms it up and lets it out
Because heat is coming out of the reaction, that means it is losing energy
Candle wax typically floats on water due to its lower density, which is around 0.8 to 1.0 g/cm³ depending on the type of wax.
