Question

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

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

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.

Answer 1

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

When liquid water solidifies the molecules form a more ordered lattice, lowering their potential energy; that excess energy is released as heat (the latent heat of fusion) to the surroundings.
