WebJan 28, 2024 · Is water freezing to ice an exothermic or endothermic process? Chemistry Thermochemistry Thermochemistry of Phase Changes 1 Answer anor277 Jan 29, 2024 Well it's a bond-making process........ Explanation: And bond-forming processes are … WebAs aresult, the frezing of water is an exothermic process because heat is being removed from the system. An endothermic process would imply that heat must be supplied to the system. That is clearly not the case here, since providing heat would actually increase the average kinetic energy of the water molecules.
