When does the volume of wax increase when it is heated while that of water reduces?
The volume of wax increases when heated because it expands due to the heat causing its molecules to move faster and spread apart. In contrast, the volume of water reduces when heated as it transitions from a liquid to a gas (steam), which results in decreased volume due to the increased distance between water molecules.
What is the Paraffin Wax freezing Point?
The freezing point is the same as the melting point; it is the point at which the paraffin transitions from solid to liquid. 37 °C (99 °F)
What is the difference in freezing point and melting point of wax?
The melting points of BEE'S wax is 45C, 113F Carnauba (a vegetable wax) 78-85C, 172.4-185F. Paraffin (a mineral wax) 47-65C, 116.6-149F. what about molten candle wax? But the freezing point of BEE's wax is usually around 33C.
Can boiling water melt candle wax?
Yes, boiling water can melt candle wax. The heat from the boiling water will transfer to the candle wax and cause it to melt.
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.
What happened to the volume of the water and the wax after freezing?
At freezing the volume of gas increase.
How do you separate water from wax?
One way to separate water from wax is through the process of distillation. By heating the mixture, the water will evaporate and can be collected, leaving the wax behind. Another method involves freezing the mixture, as water and wax have different freezing points, allowing them to be physically separated.

Why density of wax is less than water?
The density of wax is less than water because wax is less dense than water. In other words, the mass of wax for a given volume is less than the mass of water for the same volume. This is why wax tends to float on water.
If wax is melted then will its volume go up or down?
If solid wax is melted it becomes a liquid. In general the liquid which results from the melting of a solid has a greater volume than the original solid, though there are exceptions. One of the most important is to do with water. Usually if a liquid is cooled it loses volume and becomes more dense (heavier) and the heavier part will try to sink to the bottom. If this happened when water cooled close to freezing point, water in a pond, lake, river would sink to the bottom with the freezing water at the very bottom. A pond could thus become frozen solid, but water behaves in a curious way. From a temperature close to 4 degrees Centigrade down to the freezing temperature of zero degrees centigrade the water gradually expands and rises to the top of the lake. This means that except in the most shallow ponds the fish and other water-life have their supply of water guaranteed. A real life saver!

Is melted wax becomes solid an example of freezing?
Yes, melted wax cooling and solidifying is an example of freezing. Freezing is the process in which a liquid changes into a solid state due to a decrease in temperature.
Can the car be waxed in freezing temperatures?
It is not ideal to wax a car in freezing temperatures because the wax may not bond properly to the paint surface. It is recommended to wait for a day with milder temperatures above freezing to ensure the wax application is effective.
What is the volume of 8 grams of wax?
The volume of a substance like wax is dependent on its density. Without knowing the density of the wax, it is not possible to calculate the volume from the mass alone.
How much water leaks from a broken toilet wax ring?
3.14159 x the opening and then get the pressure / volume from the flushometer
What is the freezing point of molten candle wax?
range from 47oC to 81oC
Can wax be dissovled in water?
No, wax and water are immiscible.
