kerosene
kerosene has got higher ignition temperature.
Paper and kerosene oil are commonly used to start fires because they are flammable materials that ignite easily and create a strong initial flame. Paper provides a quick burst of heat to ignite the wood or coal, while kerosene oil is a liquid fuel that can help sustain the fire until the wood or coal catches fire properly.
300 degrees
The ignition temperature of oak wood typically ranges from about 300 to 400 degrees Celsius (572 to 752 degrees Fahrenheit). This is the temperature at which oak wood can catch fire and sustain combustion. Factors such as moisture content and the presence of additives can influence the exact ignition temperature.
Wood needs to reach its ignition temperature to catch fire. When heated only slightly, the temperature may not be high enough to cause ignition. Additionally, a lack of sufficient oxygen or fuel can also prevent wood from catching fire when heated a little.
Wood does not increase in size when soaked in kerosene because kerosene is a non-polar solvent that does not interact with the polar molecules in wood's cellulose and lignin structure. Unlike water, which can swell wood by penetrating its cell walls and forming hydrogen bonds, kerosene does not have the same affinity for wood fibers. As a result, the wood remains stable in size when exposed to kerosene.
Kerosene does not increase the size of wood because it is a non-polar solvent that does not interact strongly with the polar molecules in wood, such as cellulose and lignin. When wood absorbs kerosene, it may swell slightly due to the solvent's presence, but this effect is minimal and temporary, as kerosene does not chemically bond with the wood structure. Additionally, kerosene acts primarily as a fuel rather than a moisture source, which is necessary for significant wood expansion.
The ignition temperature is about 250 Celsius for ordinary wood.
This is because the specific heat capacity of the wood is more than the kerosene oil. So, the wood takes time to burn but burns for longer period than the kerosene oil.
Kerosene is not needed to burn wood. If you use a layer of scrunched up newspaper, some small kindling on top of the paper, and progressively larger pieces of wood as the fire is starting, no kerosene or other product is necessary if the wood is seasoned and dry.
No, wood cannot be used to melt copper because the temperature required to melt copper (1,984°F or 1,085°C) is much higher than the ignition point of wood (around 572°F or 300°C). To melt copper, a heat source such as a furnace or a torch that can reach the required temperature must be used.
Wood typically ignites at temperatures between 400°F and 500°F (204°C to 260°C). However, the exact ignition temperature can vary based on the type of wood, moisture content, and other environmental factors. Once the wood reaches its ignition point, it can catch fire and sustain combustion.
