No, what is left of the log is reduced in mass but mass is conserved as the remainder is ashes and tiny particles that rise as smoke,
When a log burns in a fire, it undergoes a chemical reaction called combustion. The heat from the fire causes the wood in the log to break down and release gases and smoke. The remaining solid material turns into ash.
When a log burns in a fire, the chemical reactions that take place involve the wood combining with oxygen in the air to produce heat and light. This process is known as combustion, where the wood undergoes a chemical reaction that releases energy in the form of heat and light.
A log burns slowly because it has a higher moisture content and is denser, requiring more heat to ignite and sustain combustion. In contrast, a wood splinter burns quickly because it is thinner, less dense, and has a lower moisture content, allowing it to ignite and burn rapidly.
Density is a measure of how much mass is contained in a given volume. It is calculated by dividing an object's mass by its volume. Denser objects have more mass packed into a smaller space, while less dense objects have less mass in the same volume.
It is the release of the chemical energy stored in the wood - however remember this chemical energy was originally trapped form the sunlight as the tree grew, so the ultimate source of the energy is the Sun.

yes
IT'S chemically because fire is a chemical
In a chemical reaction the mass of reactants is equal to the mass of products; burning is a chemical reaction.

light the fire in the pit (during fall or summer) with your flint. douse the fire (during spring) and take the burnt log out of the fire pit
it turns into ash
Same thing.
Wood such as paper will burn at 451 degrees Fahrenheit. How it necessarily burns is subject to how much moisture is actually in the wood.
Technically "no", Practically "yes": Technical Answer: Weight of the log in pounds x 8,000 btu/pound = btu total fire load, which would not change by fragmenting the log into chips. This answer ignores the burn time required in each case, see practical answer below. Practical answer: Duration of fire time in minutes/hours required to completely reduce the entire mass of wood to heat, light, smoke and ashes is dependent upon the surface to mass ratio, or simply put, the log would take longer to burn up than would the same mass of wood reduced to chip sized particles. The consequence: the intensity of the chip fire would peak at an earlier and higher heat release rate than would the log fire, thus the practical answer: at peak intensity the chip fire would require a higher water flow rate in gallons per minute (GPM) to control/extinguish than would the log fire.
