Is candle wax burning a physical change?
For the wax, yes. It changes to a liquid and then back to a solid. But some of the wax is also consumed in a chemical change as it oxidizes, along with the burning wick.
What is the energy flow diagram of a burning candle?
The wax in the candle contains chemical energy. When you burn the candle the chemical energy is transferred into heat (thermal) and light energy. :)
What is the effect of candle wax?
Candle wax is the fuel a candle uses to keep burning. So, I guess the effect of the wax is the candle keeps burning.
Why burning of candle is a physical and chemical change?
CHEMICAL
What is the physical and chemical change that occurs when a birthday candle is lit on a cake?
There are multiple physical changes and chemical changes that occur when a candle burns. One physical change is that the candle melts back into liquid wax. One chemical change is flame burning on the wick.
How do you know that a burning of candle wax is an exothermic change?
Because heat is coming out of the reaction, that means it is losing energy

Is a candle burning a physical change?
It is actually both. The burning of the wick involves a chemical change. The physical change is the wax.
Is it a physical change when a candle changes size by burning?
Yes, because the candle wax isn't actually burning, just melting
How can you change the burning time of a candle?
It can be changes by changing the size or the thickness of the candle, or changing the nature of the wax.
How do you know that the burning of candle of wax is an exothermic change?
An exothermic reaction involves the release of heat into a system. The burning of a candle is combustion reaction. Combustion reaction release heat, and this can be detected and measured by the burning of a candle's wax. From these testable observations it is determined fact that candle burning is indeed exothermic.
What are the physical properties of the wax in the burning candle?
Wax will melt and is converted from solid to liquid. It is a physical change.
What a the physical properties of the wax in a burning candle?
Wax will melt and is converted from solid to liquid. It is a physical change.
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
Why is the burning of a candle a physical change?
The wax melts, it can solidify into a solid again.
