Burning is a chemical change. Any burning process is the thermal decomposition of the material that is burnt. The flame that is seen during the burning process (for solids and liquids) is not a physical entity but actually the chemical disintegration of the gas that is formed from the decomposition of the burning element. (Correction - it can be a physical entity. The yellow or white flame is actually white hot carbon particles that cool off and produce soot). Since, in case of gaseous burning the material is already in the gaseous state it directly gets thermally disintegrated into simpler products. For example: * When gasoline burns it first get converted into its vapor which then decomposes into simpler matter (carbon or simple carbon based compounds). * When gaseous methane burns it gets converted to Carbon and Hydrogen gas (correction - sorry, no. It gets converted into carbon dioxide and water. It cannot get converted into hydrogen because that itself would burn to form water). In both these cases the burning process is chemical, the flame is the component gas at high temperature, and the color of the flame is characteristic of the chemical composition of the burning gas.

Is the burning of methane gas in a cooker a physical or chemical change?
The burning of methane gas in a cooker is a chemical change. In this reaction, methane reacts with oxygen to produce carbon dioxide, water, and heat energy. This results in a new substance being formed with different chemical properties than the original methane gas.
Is hydrogen burning a physical or chemical change?
The burning of hydrogen is a chemical change because it involves the rearrangement of the atoms in the hydrogen molecule to form water. This process also releases energy in the form of heat and light.
How does LPG gas burning on gas stove involve chemical and physical changes?
When LPG gas burns on a gas stove, it undergoes a chemical change as it reacts with oxygen to produce heat, light, carbon dioxide, and water vapor. This is a combustion reaction. The physical change involved is the change in state of the gas from a liquid to a gaseous form as it is released from the cylinder and then burns.
Is a burning a gas into exhaust fumes and other gases a chemical or physical change?
Burning a gas to produce exhaust fumes and other gases is a chemical change. This is because the burning process involves a chemical reaction where the gas molecules are broken down and rearranged to form new molecules, resulting in the release of energy and the formation of new substances.
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.
Is burning gas a physical or Chemical?
a chemical change
Is burning of gas a physical or chemical Chang?
It is a chemical change.
Why is a burning gas in a a stove a physical change?
Burning is a chemical process !
Is changing of gas into fire is a chemical or a physical change?
i think chemical change because by burning of gas,a new gas is formed.
Is the burning of methane gas in a cooker a physical or chemical change?
The burning of methane gas in a cooker is a chemical change. In this reaction, methane reacts with oxygen to produce carbon dioxide, water, and heat energy. This results in a new substance being formed with different chemical properties than the original methane gas.
Consider the burning of gasoline and the evaporation of gasoline which process represents a chemical change and which represents a physical change?
The burning of gasoline represents a chemical change because it involves a reaction with oxygen to produce heat, light, and new chemical compounds. On the other hand, the evaporation of gasoline represents a physical change as it involves the gasoline changing from a liquid to a gas without any change in its chemical composition.
Is gas burning in a car is a chemical or a physical?
physical
Is gas burning in an engine a chemical change?
Of course, it is a chemical change.
Is hydrogen burning a physical or chemical change?
The burning of hydrogen is a chemical change because it involves the rearrangement of the atoms in the hydrogen molecule to form water. This process also releases energy in the form of heat and light.
