What is the difference between melting and burning wax?
Melting is a change of state from solid to liquid. Burning is reacting a substance with oxygen, otherwise known as combustion.
What physical changes happen when a candle is lit?
There are many things that physically chance when a candle burns. The wick burns, and turns into ash, and wax of the candle melts and runs down the sides of the candle or container.
Can you give examples of solids turning into liquids?
Ice cubes are solid in the freezer, but will change into their liquid state (water) when left on the counter. Hope this helps...A square on the table is a solid as well.
Do solids have a high or low melting point?
That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.
What happens when a candle is alight and there is a chemical change?
the candle wax changes state from a solid to a liquid and that is the chemical change when a candle is alight the hydrogen and carbon react with the oxygen to produce heat and light energy. the heat energy then causes the wax to turn from a solid to a liquid. But then a lot more is involved. because you need both a chemical and a physical change to explain what happens. the candle turns from a solid, to a liquid because it's melting, and then turns into a gas because it's condensating and then evaporating. This is because the hydrogen and carbon which means hydrocarbon basically- combust with the air (react) causing new substances to occur in it's place. until eventually there is no wax there left because it's all condensated and evaporated. I'm in yr 7 as a write this for a project, and i know others need this help to=]. Oxygen is simply h20 with some other included particles, and h20 simply stand for water (with a small 2) . A flame needs different substances to be able to be a flame, for example the fire triangle, the three main things a flame needs to be a flame, heat, the energy to produce the flame, oxygen, usually from the air, and fuel, a substance that burns for the flame. there is a lot more involved also, such as monoxide that is produced when is occurs that it's condensating the hot wax. also when the liquid is turning back into a solid it's called freezing solidification, another simple chemical equation for it is: (hydro carbon(c10H22, or higher hydro carbon) (5) +02(g)==7 Co2(g) + H20(g). when it combust with the air. Good luck with that answer. =]. p.s colouring diagrams helps if your doing a project. x
What is the difference between melting and burning wax?
Melting is a change of state from solid to liquid. Burning is reacting a substance with oxygen, otherwise known as combustion.
Is melting candle wax a solid?
it's both solid and liquid. When it's cooled it's a solid, then when it is heated it's a liquid.
What type of process occurs when solidified wax is converted to liquid wax on heating?
The process that occurs when solidified wax is converted to liquid wax on heating is called melting. Melting is a physical change in which the solid wax absorbs heat energy, causing the molecules to vibrate and break free from their fixed positions, transforming the wax from a solid to a liquid state.
Is candle wax solid liquid or gas at room temperature?
Solid.
What changes of state occur when wax runs down the side of a candle?
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).
Is a hot candle wax solid liquid or gas?
Hot candle wax is a liquid. When the wax is heated, it melts and transforms into a liquid form.
Is candle wax melting chemical or physical change?
It is a physical change, from a solid to a liquid. The chemical composition of the wax remains unchanged.
List of solids which changes its state when heated?
Ice (solid water) changes to liquid water when heated. Wax solid changes to liquid wax when heated. Metal becomes molten when heated to its melting point. Paraffin wax solid changes to liquid paraffin wax when heated.
What is the definition of melting?
Melting is when a solid becomes hot and "melts" into a liquid. (wax)
Is a candle an example of sublimation?
No, a candle is not an example of sublimation. Sublimation is the process by which a substance transitions from a solid directly to a gas without passing through the liquid phase. Candles involve the solid wax melting into a liquid state and then being converted into gas through combustion.
Is wax melting an irreversible reaction?
Wax melting is a reversible physical change, not a chemical reaction. When wax melts, it changes from a solid to a liquid state due to the application of heat. Once the heat is removed, the liquid wax will solidify back into a solid form without undergoing any chemical changes.
What change of state is it when a candle wax becomes a liquid?
The change of state is melting. When a candle wax is heated, it transitions from a solid state to a liquid state.
