Question

Is freezing an endothermic or exothermic process? How do you know?(1 point)

Freezing is exothermic because as water bonds into ice, the energy from bond formation is released and heats up the surrounding environment.

Freezing is endothermic because as water bonds into ice, the energy from bond formation is released and heats up the surrounding environment.

Freezing is exothermic because as water bonds into ice, the bonds absorb energy from the environment in order to change states.

Freezing is endothermic because as water bonds into ice, the bonds absorb energy from the environment in order to change states.

Answer 1

Freezing is exothermic because as water forms the stronger hydrogen-bonded structure of ice, bond formation releases energy to the surroundings (so the environment is warmed). The correct choice is the first one.
