Chemistry - Thermochemistry - Exothermic and endothermic reactions - Hot or Cold Reaction?
Sort 10 everyday reactions into EXOTHERMIC (releases heat, feels hot) or ENDOTHERMIC (absorbs heat, feels cold). Exothermic: Burning wood, hand warmers, combustion of gasoline, rusting (slow but releases heat), neutralization (acid+base → warm). Endothermic: Ice melting, instant cold packs, photosyn
