Why does rubbing of a matchstick on a rough surface lights up?
The rough surface causes a lot of friction when the matchstick rubs against it. Friction causes heat (try this for yourself by rubbing the palms of your hands together- they feel hot. Then consider how smooth our skin is in comparison to the rough surface, so you appreciate how much heat it generated.) The heat causes the wood of the matchstick to set alight. Actually, the head of the matchstick is coated in a more flammable substance (phosphorus), which makes lighting even easier.
What is the waste energy in matches?
When a matchstick is struck, the friction creates waste energy in the form of heat and sound. This waste energy is not used for the intended purpose of lighting the match and is lost to the surroundings.
What is the temperature of burning matchstick?
The temperature of a burning matchstick varies between 71 and 94 degrees Centigrade
Why it is difficult to light a matchstick by striking it on a smooth surface?
A matchstick needs friction to ignite, which is provided by the rough striking surface on the matchbox or matchbook. A smooth surface lacks the abrasiveness required to generate the necessary heat to ignite the matchstick.
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.
Lighting a match a physical change or chemical change?

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.
An example of a physical change would be?
Burning of a matchstick.
How can you make the chemical energy in the matchstick useful?
Strike the match and start it burning then it can be used
Why should the matchstick be held in 1 cm below the nozzle when lighting the burner?
Holding the matchstick 1 cm below the nozzle helps prevent the flame from traveling back into the gas tube. It creates a safe distance for the ignition process and reduces the risk of gas leaks or flare-ups. It also allows for better control and visibility when lighting the burner.
