Is burning a phase change. Explain?
Ans: No because, its a chemical reaction
Burning is a chemical reaction; the products of this reaction are gases, but the expression change of phase is used for vaporization, melting, deposition, etc.
Phase Change
No, burning anything is a chemical change.
Tearing a tissue paper is a physical change.
Lighting A Match
A match burning is an example of chemical energy transitioning to light and heat energy.
A chemical reaction suggests that something is altered(typically non-reversible)down to the chemical elements. A physical change is changing the appearance of an object(is usually reversible) A match burning changes the match down to a irreversible level
Burning a match is an exothermic change because energy is being released.
No, burning anything is a chemical change.
A match burning is a chemical change. Salt dissolving in water is a physical change.

Melting: change of phase, a physical phenomenon without change of the composition. Burning: a reaction of oxydation, a change of composition - a chemical change.
it is a chemical change.... so i would assume it is a chemical matter. it is a chemical change because of phosphrosus on the end of the match changes in to co2
The most common example is the burning of a match or wood (or anything really).
ice melting
chemical energy to light and heat energy
While the match is burning it has thermal energy
Tearing a tissue paper is a physical change.
To match 2 phase line voltage it has to be the same voltage.
