How does the energy from a wood fire actually come from the sun?

light (sun) ----> photosynthesis (chemical energy)
mechanical energy ----> cut down the tree
work ----> move the tree
store chemical energy from sun ----> light
so basically photosynthesis gives the tree chemical energy, and when it is burned, the chemical energy is released causing light.

∙ 9y agoThe combustion of wood converts the chemical energy stored in the wood into thermal energy. The chemical energy comes from the tree converting glucose into cellulose and photosynthesis converting sunlight, carbon dioxide and water into glucose.

Wood has energy while a burning fire has energy?
Wood has chemical potential energy, when combustion occurs, you have fire. Fire is mostly heat and light energy.
How wood converted to heat energy?
This goes back to the second theory of thermodynamics....Matter is not created or destroyed...only altered. In this case the wood is altered into fire and the fire produces heat.
Why do you get shocked when you rub wood and fur together?
When you rub wood & fur together, a heat/electric energy is released. this energy is called "friction". Friction moves so fast that the "shock" you feel is actually the energy moving to your body.
What is the starting energy of a wood on a log fire?
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.
What does it mean when it says what forms of potential energy were displayed in the illustrations?
I assumed this question is on symbol interpretation. There are symbol on energy, for instance atom is for nuclear energy, lightning is for electricity, fire is for thermal energy, wood/plant is fuel derived from wood/plant, oil barrel for oil. From above example, wood/plant fuel is chemical potential and nuclear fuel is nuclear potential energy.

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.
How can forest be used as energy source?
The wood can be burned in a fire.
What are the sources of heat energy from 1940-1960?
Wood and coal fire :)
What burns on a fire?
What burns in a wood fire is the gas inside the wood, and the heat breaks down particles in the wood, causing the bonds that were broken to release energy and the entire compound then combusted.
How can chemical energy transform into thermal energy into light energy?
The transformations that you describe are quite common. Fire does this. Chemical energy in (for example) wood, transforms into heat when you burn the wood, and when you get enough heat, you will then also get light; in a fire, you get a glowing, very hot gas called plasma.
How can chemical energy transform into thermal energy then into light energy?

Which one is more easy to catch fire straws or wood?
It is very interesting to find out that straws are actually more easily to catch fire than wood...!
How does wood catch on fire?
wood catches on fire because of all the carbon and hydrogen stored inside. there is also the energy from soaking in the sun and absorbing it's radiation.
How a change in thermal energy causes matter?
A burning wood fire, when cooled down or extinguished, leaves wood ashes.
What are some examples of chemical energy conv erted into light energy?
Fire The wood is a chemical energy and the fire (gasoline) is a chemical energy the heat from the fire obviously gives off heat and the "crackles" you hear gives off sound energy and the flame gives off light energy
What are Non commercial energy resources?
fire wood,agricultural waste and dried dung
