Burning endothermic or exothermic
WebDecomposition reactions can be exothermic or endothermic, depending on the chemical energy of the substances. ... Good question. Actually, burning is an exothermic reaction as it releases heat. The energy which is first given to the system is known as activation energy, the minimum energy required to start the reaction. ... WebApr 11, 2024 · 3. Feels warm to the touch: Since energy is released to the surroundings, an exothermic process often feels warm to the touch. 4. Examples: a. Combustion: Burning of fuel, such as wood or gasoline, releases heat energy to the surroundings. b. Freezing of water: When water changes from liquid to solid state, the lost energy is released as heat. c.
