When a candle burns both physical and chemical changes take place Identify these changes?
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!
How can you explain the physical change of a burning candle using the big idea of energy?
The physical change of a burning candle can be explained using the big idea of energy by understanding that the burning process releases stored chemical energy in the wax as heat and light energy. The chemical bonds in the wax molecules break, converting chemical energy into thermal and electromagnetic energy. This change is an example of the conservation of energy principle, where energy is transformed from one form to another but not created or destroyed.
What is an example of phsical change?
Wax melting from the candle.(it has the same properties in liquid state too)
What type of reaction occurs when a candle is burned?
The burning of a candle is a chemical reaction called combustion, which involves the candle wax (a hydrocarbon) reacting with oxygen in the air to produce carbon dioxide, water vapor, and heat. This reaction releases energy in the form of light and heat.
What energy change occurs when a candles burns?
When a candle burns, potential energy stored in the chemical bonds of the wax is converted into heat and light energy. The chemical reaction of the wax with oxygen releases energy in the form of heat and light, producing the flame and providing illumination.
Is burning wax a physical or chemical change?
Burning wax is a chemical change. If you are burning something, it will always be a chemical change.
Is balls of wax forming when melted wax is poured into ice water a chemical change?
No, the formation of balls of wax when melted wax is poured into ice water is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of the substance, which is not occurring in this case.
Is Melted Wax A Chemical Change chemical Property?
Melted wax is a physical change, not a chemical change. When wax melts, its state changes from solid to liquid without any change in its chemical composition. Chemical properties refer to how a substance interacts with other substances in a chemical reaction, and melting wax does not alter its chemical properties.
Is wax hardening a chemical change?
NO... physical
Is wax melting a chemical or physical or chemical property?
Physical change. The wax was solid and now it is a liquid. All phase changes are physical changes.
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.
Is candle wax hardening a physical or chemical change?
The hardening of candle wax is a physical change. This is because the wax simply changes from a liquid to a solid state without any change in its chemical composition.
Is melting wax an chemical change?
no because the wax will always stay the same. it is a physical change
IS bees creating wax from sugar a physical or chemical change?
The process of bees creating wax from sugar is a physical change. It involves the physical transformation of the sugar molecules into wax molecules without any change in the chemical composition of the substances.
What physical and chemical changes occur when a wax candle burn?
Some wax burns, and as it does so, chemical changes occurs. Wax converts to CO2, CO, and H2O. That is an exothermic reaction The rest of the wax melts with the increased temperature. That is the physical change.
Is burning of wax chemical or physical change?
it is a chemical change because it produces gases
Is a melting wax a physical or chemical property?
Melting wax is a physical property because it does not change the chemical composition of the wax when it transitions from solid to liquid state. The process just involves a physical change in the state of matter.
