Endothermic meaning gcse

WebAn endothermic chemical reaction is a reaction that occurs by absorbing heat energy from the surroundings, and by doing so, will cool down the surroundings of the chemical reaction. The heat energy that is absorbed by the chemical reaction process essentially ‘steals’ this from the energy of the particles that surrounds the reactant particles.
