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 fuel in a car a chemical or physical change?
It would be a chemical change because it is burning. Like a newspaper on fire.
Is a burning a gas into exhaust fumes and other gases a chemical or physical change?
Because combustion (burning) produces substances with new chemical properties, this process results in a chemical change.

i think chemical change because by burning of gas,a new gas is formed.
Is hydrogen burning a physical or chemical change?

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 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).
