chemical energy
Potential
Burning coal has chemical potential energy, because the energy is stored up in the bonds between the carbon molecules, and when the coal is burned, the stored energy is released and transformed into heat, light, and even sometimes sound energy.
chemical energy to light and heat energy
There are many energy changes which take place when burning a match. First, kinetic or movement energy is used to scrape the match. Then, the chemical energy stored in the match becomes heat energy of the flame. I am not familiar with your use of the term physical energy, but if by this you mean kinetic energy then yes this would be an example of physical energy into chemical energy.

While the match is burning it has thermal energy
A match burning is an example of chemical energy transitioning to light and heat energy.
Burning a match is an exothermic change because energy is being released.
The energy given off by the burning of a match is called thermal energy. If you want to know the amount of energy, you then need to have more information related to the mass and material of the match.

The energy liberated by burning the whole match is the weight (0.2grams ?) times heat of combustion of the wood - about 20kJ per gram so a few kilojoules as you almost never burn it completely. Mike
when burning coal it gives off heat energy
