Those reactions are said to be exothermic.
only nuclear reactionsChemical reactions that release free energy are called exergonic reactions. Fire and cellular respiration are examples of exergonic reactions.
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.
Chemical reactions that involve bond-breaking tend to absorb energy from the surroundings, making the surroundings cooler. Chemical reactions that involve making bonds release energy, which makes the surroundings hotter. An example of a temperature change in a chemical reaction is when a burning fire produces heat.
Neither. The sun is made of superheated gas, mostly hydrogen and helium. It is similar to fire in some respects, but it is not actually burning. At its core the sun carries out nuclear fusion, a process that releases many times more energy than combustion does.
Fire Burning was created in 2008.

Respiration (turning food into energy), wood into fire etc
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 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.
That depends on what you are burning, an example: CH4 +2O2 -> CO2+2H2O + energy This is called a combustion.
fire chemicals
Its called "fire".
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.
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.
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.
