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.
Ice (solid water) will float easily in its liquid form due to its lower density compared to liquid water.
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!
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.
Can someone please help me!!! once i switch it of it floats back to the bottom and i don't know why? The wax and liquid are different densities. Density changes with temperature. When the wax is near the heat source, its temperature increases and it becomes less dense compared to the liquid and then it floats to the top. When it gets to the top, it cools down because it is farther from the heat source. When it cools down, it becomes denser than the liquid, and it sinks. So when you turn off the lava lamp, the wax and liquid cool to room temperature, and the wax is denser than the liquid so it stays at the bottom.
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.
The wax substance is more dense than the liquid when cool and less dense than the liquid when heated. The wax moves by density convection.
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.
The wax on a candle transitions from solid to liquid as it melts from the heat of the flame. As the liquid wax drips down the side, it cools and solidifies back into a solid state. So, the changes of state that occur are melting (solid to liquid) and solidification (liquid to solid).
Candle wax is a solid at room temperature. When heated, it melts into a liquid form.
When candle wax changes from a solid to a liquid, the heat from the flame melts the wax. The heat breaks the solid wax molecules apart, turning them into a liquid that can flow. Once the liquid wax cools down again, it solidifies, forming a new layer of solid wax.
A wax candle can turn into a liquid when it is melted by heat. Once the melted wax cools down, it solidifies back into a solid state.
Hot candle wax is a liquid. When the wax is heated, it melts and transforms into a liquid form.
wax as a solid is not flammable it will melt but not catch fire.wax as a liquid will only melt.so. no^^ no. your wrong. lolwax as a solid does turn to liquid, and in a candle, for example, the wick is burning the vapour from the liquid wax which is actually very flammable.
Solid.
One ounce. No mass is lost in the phase change from solid to liquid wax.
it's both solid and liquid. When it's cooled it's a solid, then when it is heated it's a liquid.
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
