Endothermic Reactions
Endothermic Reactions
Endo - means "within" (Greek)
Thermic - means "hot" or "warm" (Greek)
Endothermic reactions absorb heat from their surroundings, this makes them cold to the touch.
Exothermic Reactions
Exothermic Reactions
Exo - means "outer" (Greek)
Thermic - means "hot" or "warm" (Greek)
Exothermic reactions release heat into the surroundings, this makes them hot to the touch.
