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.
to get different types of wood and burn them and watch and see which one burn the fastest
It is Balsa wood.
about one inch every 20 minutes
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.
Dry, seasoned and resinous pine wood burns fastest.
I would say sulfuric acid eats through wood fastest. It also has a dehydrating property that sucks the water right out of the cellulose of the wood, leaving behind charred carbon.
No it is not safe to burn it.
for wood to burn you need fire
Both. Heated wood gives off gasses that burn. Charcoal (carbon) will also burn.

Petrified wood- wood that has turned to stone. Any other wood WILL burn, some better than others.
Yes: it is a relatively soft wood, so it may burn hot and fast.
