When gas cooker gas burns with blue flame is it chemical or physical reation?
Burning is a chemical reacyion, an oxidation.
Is gas burning in an engine a chemical change?
Of course, it is a chemical change.
Is burning gas a physical or Chemical?
a chemical change
Is gas burning a physical change or chemical change?
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 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 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 natural gas burning in a furnace a chemical change?
Yes, combustion of natural gas is a form of chemical change.
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 flame a example of physical change or a chemical change?
Something burning is a chemical change because it is combining with the oxygen in the air. Ex. when you burn sugar you get c02 and water, the reason the water doesnt put out the fire is that the water is released as a gas.
Is the burning of natural gas a chemical change?
Yes
Is candle wax burning an exaple of an physical change?
Only the melting is physical (can easily be reversed by cooling down) but the actual burning (flame) is a complicated chemical set of reactions.
