when you enter a toy car on the floor and you push it whwre you want directions.what made the car move?
The energy given off by burning matchsticks is in the form of light and heat. This can be observed through the bright flame that is produced and the warmth that is felt when a matchstick is burning.
The burning of a candle gives off heat. This is because the chemical reaction of the wax with oxygen releases energy in the form of heat and light.
Exothermic Trishi! =)
From chemically burning the nutrients.
The energy given off by burning a matchstick is mainly in the form of heat and light. The heat is a result of the exothermic combustion reaction that occurs when the matchstick is ignited, and the light is emitted as a by-product of the combustion process.

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.

Those reactions are said to be exothermic.
it is thermal energy .

The answer to the riddle "tear one off and scratch my head what was red is black instead" is a matchstick. When you tear a matchstick off from the matchbox and strike (or scratch) its head, the red phosphorus ignites and turns into a blackened residue after burning. Thus, what was once red (the match head) becomes black after use.
By burning it. The heat it lets off will be energy.
