Burning is a chemical process !
burning of candle
The burning of gasoline is a chemical change. The evaporation of gasoline is a physical change. This is a physical change because it is a change in state of matter (from liquid to gas).
Melting! A physical change would be to change something from Solid <--> Liquid <--> Gas
Natural gas, gasoline, fuel oil, coal, and LPG burning are all chemical reactions ( chemical changes ). The reactants ( fuel and oxygen ) react yielding primarily CO2 and H2O., which are different chemical species than the reactants.
This involves a change of state of the water. Before, during, and after the boiling, it remains water. So, since the substance doesn't change its character, the boiling of water is a physical change.
it is both physical and chemical change
It is a chemical change. Natural gas (UK) is a mixture containing principally methane. CH4 + 2O2 -> CO2 + 2H2O
a chemical change
Burning is a chemical change, an oxydation.
It is a chemical change.

i think chemical change because by burning of gas,a new gas is formed.
Burning a fuel is a chemical change. Two or more substances are combined and new substances are produced with different properties than the original substances. In other words the gas and oxygen in the air are combined to form carbon dioxide and smoke.
The burning of gasoline is a chemical change. The evaporation of gasoline is a physical change. This is a physical change because it is a change in state of matter (from liquid to gas).

The heat energy from the stove, which in turn comes from the burning of the chemical energy in the gas that is burning, or from the electrical energy, depending on the type of stove.
burning in presence or absence of oxygen is a chemical change.
