In very simple terms, what we generally know as fire is the result of carbon atoms (in say, wood or a fossil fuel) bonding with oxygen. When atoms bond together (as in carbon with oxygen) energy is released. In the case of combustion (fire), it is released in the form of photons (electromagnetic radiation) of certain wavelengths. These wavelengths include visible light (that we obviously see) and infrared, that we feel as heat.

Is fire positively or negatively or neutrally charged?
Fire itself is not charged with positive or negative electrical charges. It is a rapid chemical reaction involving oxygen that produces heat and light. The properties of fire are not directly related to electric charge.
Is fire heat energy?
Not quite. Heat is a result of combustion, but fire is actually chemical energy.
How much heat does fire have?
Fire, all fire, every fire consists of 3 things: Heat, Fuel & Oxygen. When all 3 are together in the right mix you have fire, if one or more elements is not sufficient then you cannot have fire. You therefore need as much heat as necessary along with the fuel & oxygen to maintain the fire. The specific answer is that the balance of the 3 must be correct. Quantifying that, however, is a different matter.
What is produced after a fire?
Fire releases heat and carbon dioxide. The carbon depends on how the fire is burnt. Unburnt hydrocarbons are released if fire is not complete.
How does evaporation cool down a fire?
Evaporation cools down a fire by using heat energy to turn water into vapor, which absorbs heat in the process. As the water evaporates, it takes away heat from the surrounding area, including the fire, reducing its temperature and slowing down the rate of combustion.
