Is lighting a chemical change?
Yes. While act of melting wax is a physical change, because you can remould it, the wax is actually what is primarily burned as fuel. You cannot unburn the wick nor the consumed wax. Remember, if it can be redone, it is probably physical and vice versa.The wick of a candle is used to light it and is used as a medium for burning the wax. As the wax is heated, it is soaked into the burning wick. As the fire burns the wax on the wick, more melted wax is absorbed into by the wick. As the wax burns down, so does the wick.
How do you keep an ice cube from melting in a science fair project?
Use clay,rubber, wax, seaweed and styrofoam
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 if the melted paraffin wax is immediately applied on the hand after heating?
You feel a very unpleasant burning sensation.
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.
What is the difference between melting of candle wax and burning of candle?
Burning a candle is the process in which the wick is burnt. The wax is there to make the wick burn slower in order to let the candle burn for longer. Melting wax is part of the process but not burning the candle itself.
What type of reaction occurs when a candle is burned?
There are 2; the melting of the candles wax is physical but the wick burning is chemical.
Is a wick necesarry in a burning candle?
Yes that is what burns the melting wax prolongs the burning time by slowly evaporating
Why melting of wax is difference than burning of wax?
Melting doesn't change the composition of a compound (substance).Burning is a chemical reaction, an oxidation - new compounds are formed.
What part of a burning candle takes place and physical change?
The melting of the wax is a physical change. The burning the of wick is the chemical change
Is it a physical change when a candle changes size by burning?
Yes, because the candle wax isn't actually burning, just melting
Is a wax burning a reversible change?
no! because burning is never a reversible change as heating is a reversible change e.g chocolate melting
Temperature of melting wax in celsius?
It depends upon nature of wax, usually wax melts between 40 to 50 Celsius.
Is there a difference between roller skate wax and skateboard wax?
No
What is the difference between natural wax and paraffin wax?
Mustard!
Is there a difference between pectin wax and paraffin wax?
yes
Why is melting a physical property of the wax but flammability in a chemical property?
Melting doesn't change the composition of a compound (substance).Burning is a chemical reaction, an oxidation - new compounds are formed.
