Does fire need energy?

Yes, fire does require energy to ignite and continue burning. This energy can come from sources such as heat, light, or a chemical reaction. Once the fire is burning, it releases energy in the form of heat and light through a process called combustion.


Wood has energy while a burning fire has energy?

Wood contains potential energy stored in its chemical bonds, whereas a burning fire releases this energy as heat and light through a chemical reaction called combustion. Consequently, the energy in the wood is transformed into thermal and radiant energy when the fire burns.


What is the chemical reaction of fire?

That depends on what you are burning, an example: CH4 +2O2 -> CO2+2H2O + energy This is called a combustion.

What is a Fuel burning in air called?

Its called "fire".


Light and heat energy are being released from the fire where is the energy come from?

The energy in a fire comes from the chemical reactions taking place as fuel is burned. When the bonds between atoms in the fuel molecules break, they release energy in the form of heat and light. This process is known as combustion.


How is a forest fire an analogy of cellular respiration?

Because cellular respiration is the process by which turning ADP into ATP, while burning a fire is just a release of energy. Cellular Respiration= gaining of energy Burning a fire=losing energy.


How does fire transform into energy?

Fire converts chemical energy stored in fuel into thermal energy and light energy through a process called combustion. The heat generated from burning the fuel can then be harnessed to produce other forms of energy like electricity or mechanical energy.


A burning fire produces what kind of energy?

Radiant and thermal


Example of energy transformation from chemical potential energy to thermal energy?

A log burning in a fire place.
