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.
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.
What one what processes is not a physical change drying wet clothes cutting snowflakes out of paper lighting a match from a matchbook?
The answer is lighting a match box because when doing so, the match goes into flames and flammability is a chemical change. When cutting a snowflake, the substances do not change, neither does it change when drying wet clothes. The person earlier said drying wet clothes, but he/she is wrong because when you dry wet clothes, the water goes through a physical change called evaporation, which is NOT a chemical change. I hope this helps. Good luck on your chapter assessments(I'm doing mine too). :)
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.
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 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.
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.
Is the ignition of matches a chemical change?
Lighting a match starts a chain reaction which boosts the materials of the match tip, the wood with oxygen. These process changes the substance chemical formula, thus chemical change happens.

Why is lighting a match considered a chemical change?
Because when the light is matched, it has a chemical reaction that makes unable to change back into it's original format.
An example of a chemical change is?
Lighting A Match
Is lighting something a physical or chemical change?
lighting is a chemical change
Which is not a physical change drying wet clothes cutting snowflakes from paper or lighting a match?
