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.

Why can log of wood no be lightened by matchstick but a paper?
For something to burn, it has to be heated to the point where it can catch fire. Wood CSN stand fairly high temperatures, and a match hasn't enough energy to raise the temperature high enough.
What do energy and matter have in common?
According to eienstiens equation E=mc^2 matter can be converted into energy. Even when you burn a wood log, the wood is converting into heat energy and light.
Why does a saw become warm when it is used to cut a log of wood. State the energy transformation taking place?
Mechanical energy is wasted due to friction. The wasted energy is converted into heat.
When wood is burned energy is released in the forms of heat and light Describe the reaction and explain why this change does not violate the law of conservation of energy?
when wood is burned, it undergoes a chemical change. the fuel is being oxidized and turned into ash and water vapor. as the flame is lit and set to the wood, energy is being transferred from the match to the log. as the log catches, it oxidizes or "burns" converting its potential chemical energy into heat and gives off radiation in the form of light. therefore no energy is being created or lost, only converted.
What is a thick piece of wood?
log
What does a log fire change into heat and light energy?
A log fire converts chemical potential energy stored in the wood into heat and light. The bonds in the wood are broken and release energy energy as they form lower energy bonds with oxygen.
What is the chemical energy in a log burning?
fire chemicals
Can you know a word for a piece of wood starting with the letter L?
a piece of wood is called log
Why can log of wood no be lightened by matchstick but a paper?

Example of energy transformation from chemical potential energy to thermal energy?
A log burning in a fire place.
What do energy and matter have in common?
According to eienstiens equation E=mc^2 matter can be converted into energy. Even when you burn a wood log, the wood is converting into heat energy and light.
A wood log burning in a fireplace what kind of energy is taking place?
Stored Chemical energy being converted to, and released as Heat energy.
What temperature does a log fire burn at?
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.
How do you light a log?
Building a fire is an art. Lighting a log normally means you have to start a fire using tinder, small pieces of wood and work your way up to the larger size. One way to 'cheat' is to use some fire starters.
How do you say log in in Spanish?
log, as in a piece of wood = madero or leño log, as in record = anotacion
Are log homes energy efficient?
YES! Log homes are greatly energy efficient and it's proven. For example, the National Bureau of Standards conducted a test to confirm the energy efficiency of log homes. The test results where: 1. During the three-week, spring heating period, the log building used 46% less heating energy than the insulated wood frame building 2. During the eleven-week, summer cooling, period, the log building used 24% less cooling energy than the insulated wood frame building 3. During the fourteen-week, winter heating period, the log building and the insulated wood frame building used virtually the same amounts of heating
Burning of wood what transformation of energy is it?
When wood burns, chemical energy is transformed into heat
