because
A lava lamp moves slowly because the heat source at the bottom of the lamp needs time to warm up the wax and make it rise, creating the flowing motion. The viscosity of the wax also affects how quickly it moves within the lamp.
As the solid candle melts to a liquid, the particles gain energy and move more quickly. This increased movement causes the particles to break away from their fixed positions in the solid structure, allowing them to flow and take on the shape of the container.
As in most substances, solid wax is more dense than liquid wax. Density, by definition, is mass divided by volume. If the volume is smaller, meaning less space occupied, than the density increases. In a solid, the temperature lowers, the molecules have less energy and are less active. Therefore, they take up less space, equalling a smaller volume. Small volume, more density.
To solidify, the paraffin has to get rid of excess heat, so the heat flow is outward.
the physical change is -the shape of the candle changes,some of the wax becomes liquid to solid. chemical change-the wick is burned *Hi just wanted to say that this person above is wrong...I mean, the wick burning would be a chemical change because it is combustion. They are wrong because the wick doesn't actually burn.The wax is absorbed by the wick which cools it off. Eventually the wick becomes too long and the top of it dries out and falls off into the wax. Fact being, the wax vapor burns. You should do some more individual research for details because there is more. Thanks!
it is liquid
No, in solid wax the molecules are closely packed and in a fixed position, while in liquid wax the molecules are more spread out and can move around freely. This difference in molecular arrangement is what gives solid wax its rigidity and liquid wax its fluidity.
A polyunsaturated liquid wax that is similar to sperm whale oil. Fatty acids, alcohols.
Hot candle wax is a liquid. When the wax is heated, it melts and transforms into a liquid form.
Well the heat transferred to the wax and the wax turned into liquid. So what the wax is doing is melting and if heat stop hitting the wax then it will freeze back again and turn into a solid and its particles start moving faster and bump into each other. When wax melts , the wax changes phase from a solid to a liquid and somehow the wax's liquid will turn back into a solid when it freezes. And when a wax melts it turns into water or something like that. Hope that helped all of you guys ur welcome
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.
Oil paintings use oil-based paints that dry slowly, allowing for blending and layering, while wax paintings use pigmented wax that dries quickly and requires heat for application. Oil paintings have a rich, glossy finish and can be easily corrected, while wax paintings have a matte finish and are more difficult to alter once dried.
Lava lamps typically contain two main liquids: a colored wax that floats in a clear or colored liquid. The wax is heated by a light bulb at the base of the lamp, causing it to rise, fall, and form mesmerizing patterns in the liquid.
Generally more energy is in a solid versus a liquid, so a wax candle will have more energy than an oil based candle which means the solid wax candle will burn out last over the oil one. Actually, I can't think of a case where the reverse is true. And btw, wax candle has around 42 kJ/g with oil candle being around ~30 kJ/g (type of oil will make a difference here). tho' i agree with most of the above, the most important part of any candle is the oil/oil byproduct/animal fat or beeswax that it is made from! a wax candle will NOT burn until it heats up enough to dissolve into an oil - which occurs between 140-160 degrees! therefore, an oil candle and a wax candle burn out at the same time!
Melted wax is often referred to as liquid wax.
When wax melts, it transitions from a solid to a liquid state due to the heat energy breaking down the molecular bonds that hold its solid structure. The molecules in the wax move more freely, resulting in a loss of shape and volume as the wax takes on a liquid form.
