Lighting a match a physical change or chemical change?
Lighting a match is a chemical change because the molecules in the matchstick undergo a chemical reaction when exposed to heat, resulting in the production of new substances like ash and smoke.
Is lighting a match a chemical change change?
Burning a match is a chemical change. Whether the act of lighting it is makes for an interesting philosophical discussion. Exactly what do we mean by lighting it? Is it the movement of striking? In which case, no, that's just motion, so that's physical. Is it the application of heat, from friction or otherwise? Again, no new substance is produced at that point, so no. Do we mean the beginning of flame? Yes, as soon as it's burning, new substances are being produced.
Is lighting of bulb reversible or irreversible change?
The act of lighting a bulb is an irreversible change because the light and heat produced cannot easily be reversed to return the bulb to its original state. Once the electrical current passes through and illuminates the filament, the light is emitted permanently.
Which is not a physical change drying wet clothes cutting snowflakes from paper or lighting a match?
Lighting a match is not a physical change because it involves a chemical reaction that produces heat and light, resulting in the transformation of the matchstick. Drying wet clothes and cutting snowflakes from paper are physical changes because they involve a change in appearance or state of matter without altering the chemical composition of the substances.
Is lighting a candle a physical or a chemical change?
It is chemica changel because it produces gas and the smoke it produce is one of the evidence that it is really a chemical change, also you can't put it back to its beginning state.
Is lighting something a physical or chemical change?
lighting is a chemical change
Is Lighting candle physical or chemical change?

Lighting a match a physical change or chemical change?
Lighting a match is a chemical change because the molecules in the matchstick undergo a chemical reaction when exposed to heat, resulting in the production of new substances like ash and smoke.
Is lighting a match a chemical change?
Yes, lighting a match is a chemical change because the chemicals in the match head undergo a chemical reaction when exposed to heat from friction, resulting in the release of energy in the form of light and heat.
Is lighting your match a physical or chemical change?
Mainly chemical (oxidation).
What processes is not a physical change drying wet clothescutting snowflakes out of paper lighting a match from a matchbox?
lighting a match from a matchbox is a chemical change.

Is silver melts when using a blow torch a chemical or physical recation?
It is a physical reaction. Melting is a physical change because it does not change the chemical composition of the substance.
Is lighting a match physical change?
This is a little tricky. Striking a match is a physical act, but it does induce chemical changes. It depends on exactly what you mean by "lighting", ultimately. The end result is definitely a chemical change.
When did the torch relay for the 2008 Olympics start?

Is lighting a chemical or physical change?
Lighting is a physical change, not a chemical change. When a light switch is turned on, the flow of electricity through the bulb causes it to emit light, which is a physical reaction. No new substances are formed during this process.
Is lighting a match from a matchbox a physical change?
Yes, lighting a match from a matchbox is a chemical change, not a physical change. When the match is struck, the chemicals on the match head react to produce heat, light, and a flame. This transformation is a chemical reaction, not just a change in physical state.
