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

Why do colered candles burn faster than white candles?
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.
How does wax burn?
Heat from the flame melts the wax. The molten wax is drawn up the wick by capillary action. Heat from the flame vaporizes the molten wax in the wick as the wax enters the flame. The hot wax vapors burn as they mix with air.
What one of these has the highest density Mercury or wax?
Mercury
What is the depented variable of a lava lamp?
The independent variable is the heat of the light bulb, the dependent variable is the heat absorbed by the wax substance (or other convective liquid) which makes the substances in the lamp move due to density convection.
What burns on a candle the wick or the wax?
the wick Burns but it produces heat that melts the wax
Why cant you change wax into a candle?
You can, but you need a mould, and heat.
Is wax melting a physical or a chemical?
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.

I had to hotup the wax to clean the pot or I had to heat up the wax to clean the pot?
'heat up' the wax!!
Density of candle wax?
Candle wax or paraffin has a density of about 0.9 g/ml , this is lighter than water.
Does wax paper absorb heat?
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.
What melts wax?
Heat Heat

What is the density of candle wax?
The density of parafin wax is about 0.93 g/ml - less dense than water. Liquid wax is less dense than that, but I am now sure of the value.
Which absorbs more heat wax paper or black paper?
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
How do you know that a burning of candle wax is an exothermic change?
Because heat is coming out of the reaction, that means it is losing energy
Does candal wax float and what is its density?
Paraffin wax has a density of roughly 0.8 gm/cm3 . It will float in any fluid whose density is greater than roughly 0.8 gm/cm3.
