kerosene has got higher ignition temperature.

This would be done by shaving off some of the wood to make the pitch higher and adding more wood to make it lower.
Humidity affects the sound of a violin by influencing the instrument's wood and strings. Higher humidity can cause the wood to absorb moisture, leading to a slight increase in mass and a damping effect, which may lower the pitch. Conversely, lower humidity can dry out the wood, potentially making the sound brighter and slightly higher in pitch. Overall, changes in humidity can alter the tonal quality, but the pitch shift is typically subtle.
Like most woodwinds, the lower-end instruments will be made of plastic and the higher-end or professional ones are made of wood. This is done because in general plastic is tougher to break than wood. There is also a large difference in cost between plastic and wood instruments, especially with the bassoon.
often plastic. However originally and currently for higher quality instruments as the name implies from wood. Top clarinets such as my Le Blanc are made from Black African Rosewood.
kerosene
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.

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.
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.
There want be much of a difference in the temperature.
For Burning wood:The temperature for the piloted ignition of wood is typically about 350 °C (660 °F), whereas the spontaneous ignition requires a temperature of approximately 600 °C (1100 °F)http://virtual.vtt.fi/virtual/innofirewood/stateoftheart/database/burning/burning.html
