because iron doesn't burn...it melts.
Locust wood will burn faster, it is softer than oak.
yes
Paper burn faster than plastic due to its thick texture.
Sand doesn't burn at all, so, yes.
yes but it will burn faster than most wood and make sure its about 6 months old
Wood dust has a higher surface area compared to a block of wood, allowing for more oxygen to come in contact with the wood particles. This increased oxygen exposure accelerates the combustion process, causing wood dust to burn faster than a block of wood.
The thermal conductivity, and thermal capacity of iron is a lot higher than for wood. So when you touch wood, a little heat from your finger warms the wood just at that place and isn't conducted away. But for iron, it's as though your finger is trying to heat the whole piece, the heat conducts away rapidly and your finger then keeps trying to supply more until it is as cold as the iron. So the iron feels colder - just because it doesn't warm under your finger like the wood.
Less dense wood will burn fastest, such as balsa wood. In general, the faster a tree grows, the less dense the wood from that tree will be.
Under normal circumstances, wood will burn first because it has a lower temperature of combustion than metal. That means a stick will catch fire and burn faster than a piece of steel pipe the same size. In fact, under those normal circumstances mentioned, the stick will burn and be reduced to ash while the steel pipe will not be affected. Many times structures will burn and the steel water pipes will be left only blackened after all the wood has been consumed by the blaze.
Smaller surface area, Wood shavings are generally drier than a log of wood, because of the general density of the wood itself. Wood shavings are in turn, easier to burn because of the small amount of moisture in them, therefore, they burn faster, and easier.
Normally soft wood would burn fastest. It actually depends on the density of the wood and the amount of pitch or sap still held by the wood. For instance, soft woods such as pin and cedar, when very dry, burn very fast. However, English brown oak, a hard wood will burn as fast or faster than pine. Balsa, also technically a hardwood, burns very fast. The denser the wood, the slower the burn.
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.
