Answer No we cannot burn a piece of wood by bringing a lighted matchstick near it. When a lighted matchstick is brought near a piece of wood it does not start burning because the ignition temperature of the wood is higher than a piece of paper. A matchstick can light a tiny splinter of wood but not a big log of wood.
Why does a log of wood not burn by a matchstick but a paper does?
A substance burns only when it reaches its ignition temperature, as paper has a lower ignition temp. than that of log of wood, hence can be burned by a matchstick, but a log of wood needs more energy to reach the ignition temp, hence cannot be burned by a matchstick.
Why does a matchstick not burn of its own?
A matchstick does not catch fire and burn on its own at room temperature because the ignition temperature of matchstick is higher than the room temperature. … If kerosene is heated little it will catch fire easily because kerosene oil has a comparatively low ignition temperature which is reached even on little heating.
Why should fire be put away before throwing matchstick?
Amount of oxygen or air effects combustibility in that case. When you throw the match stick into inflammable liquid, flame turns off as it doesn’t have access to oxygen to complete the process of combustion.
Why is it easier to burn a splinter than a log of wood?
Explanation: A splinter of wood has a low ignition temperature so, a burning matchstick can produce sufficient heat to attain the ignition temperature of the splinter of wood hence, a matchstick can easily light a splinter of wood. So, a burning matchstick cannot light a log of wood directly.
Does matchstick burn with a flame?
Answer Yes. A piece of paper catches fire when a burning matchstick is brought near it. … When a lighted matchstick is brought near a piece of wood it does not start burning because the ignition temperature of wood is higher than a piece of paper.
How does a matchstick burn?
Potassium chlorate is present on the head of the matchstick. When you rub the head of the matchstick on the striking surface of the matchbox, some heat is generated due to the friction. … When Sulphur, oxygen and heat come together, fire is produced. Hence a matchstick burns on rubbing it on the side of the matchbox.
Is a matchstick a fuel give reason?
On rubbing the match stick in the rough surface, the friction converts this work into heat. The heat raises the temperature of the chemical present on the match stick head to its ignition temperature. Due to this the chemical substance catches fire and the match stick starts burning.
Which substances catch fire easily?
The substances which have very low ignition temperature and can easily catch fire with a flame are called inflammable substances. Examples of inflammable substances are petrol, alcohol, Liquified Petroleum Gas (LPG) etc.
Why is matchstick rubbed against a rough surface to light it?
On rubbing the match stick in the rough surface, the friction converts this work into heat. Due to this the chemical substance catches fire and the match stick starts burning. …
What is wooden splinter?
Splinters are objects that become embedded under the skin. Most often these are tiny pieces of wood, although glass, metal, and plastic can be splinters too. Taking a splinter out as soon as you spot it helps prevent infection and makes removal easier (since the skin won’t have time to heal over the splinter).
Why it is difficult to burn a heap of green leaves?
It is difficult to burn a heap of green leaves but dry leaves catch fire easily. Explain. Green leaves have water in them. Water in the green leaves protects the leaves from reaching its ignition temperature, so it makes burning of green leaves difficult.
