Ignition of a match is a chemical process.
How many matches are in a matchbook?

Is lighting a match from a matchbook a chemical change?
because it can't be changed back into it's normal form. the smell changes, which also tells you when a chemical change is taking place.
Is a match a natural or man made light source?
A match is a man-made light source because it is created by the combination of specific chemical components in the match head that produce a flame when struck against a rough surface.
Light from a lit match comes from?
the combustion of the match head material, which releases energy in the form of heat and light. This light is a result of the incandescent particles emitted as the material burns and undergoes chemical reactions.

Is strike the match an idiom?
Yes because you are not actually hitting the match, just rubbing it sharply against the sandpaper.

When did strike on back matchbook covers?
Matchbook covers with a strike on back design were popular in the mid-20th century, typically from the 1930s to the 1970s. This design allowed users to strike the match against the back cover to light it, making it a convenient and common feature on matchbooks during that period.
How thick is a match book cover?
According to PhantomChaos of offshoreonly.com, a matchbook cover measured to about .015 in.
What year was the safety match invented?
Johan Edvard Lundstrom patented his safety match in 1855, in Sweden. He had come up with the idea of putting some red phosphorous on sandpaper inside the box of matches, with different chemicals on the match head. The match would remain unlit unless it was struck against the specially prepared striking surface. The matchbook was developed and patented by Joshua Pusey in 1889, with the striking surface on the inside. The Diamond Match Company had invented a similar matchbook, but with the striker on the outside. In 1996, they bought Pusey's patent and made him a job offer with their company. They went on to patent the first nonpoisonous match in the US.
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). :)

Which enery transformation occurs when a match is lit?
The chemical energy - sugars - in your bloodstream are absorbed by the muscle cells in your arms. Your muscles convert this chemical energy into kinetic energy (the energy of motion) in moving the match against the sandpaper surface. The movement of the match against the sandpaper surface causes friction, changing the kinetic energy into heat. The heat of friction in the matchhead causes the phosphorus coating to ignite, converting the heat of friction into heat of combustion, in which the chemical energy in the match is oxidized into radiant heat.
What are the ten good uses of friction?
fricion can be used in machines, brakes in a car, sandpaper, lighting a match and rubbers.
How does a burning match actually burn?
The match burns because of the friction between the sandpaper and the match. Try rubbing your hands together, it does the same thing! Can you feel your hands warm up? That is the same thing that is happening with the match. But no oxygen, and the fire goes out!
