What else can I help you with?
What must be added to wax to melt?
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.
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 is the change of state in a lit candle?
The change of state in a lit candle is from solid (wax) to liquid (molten wax) to gas (vaporized wax) as the heat from the flame melts the wax and turns it into vapor that burns, releasing heat and light.
Why does a candle wax melt when heated?
Candle wax is made of hydrocarbons, which have a low melting point. When heat is applied, the molecules in the wax gain energy and move more quickly, causing the solid wax to transform into a liquid state.
Why does candle wax melt when heated?
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.
Density of candle 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.

What is the physical change in a wax taper when ligting a firwork?
When lighting a firework with a wax taper, the physical change in the wax taper is the melting of the wax due to the heat from the flame. The solid wax turns into a liquid form as it absorbs heat energy, making it easier to transfer the flame to the firework.

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.
Why do wax melts in the fire?
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.
Explain why the temperature of Wax remains constant during solidification?
it's because it releases the latent heat of fusion. Latent heat means energy is given out when a substance changes from liquid to solid without a change in temperature. and the transfer of energy doesnt change the KE of the particles, so the temperature remains unchanged. lanten heat gives rise to the change in PE of the particles during the change of state only
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!!
