Question 59

Energy is absorbed from the surroundings during the melting phase change.

During the melting phase change, energy is absorbed from the surroundings, leading to the transformation of solid ice into liquid water. This process is evident in the polar ice caps producing meltwater as they absorb heat from the environment.

A) Fog forming on the bathroom mirror when you take a shower

Fog formation occurs when water vapor condenses into tiny droplets on a cooler surface, releasing energy into the surroundings. This process is an exothermic reaction, meaning energy is not absorbed, but rather released, making this option incorrect.

B) Molten metal solidifying in a pattern mold

When molten metal cools and solidifies, it releases energy into the environment as it transitions from a liquid to a solid state. This process is also exothermic, indicating that energy is not absorbed but rather expelled, thus ruling out this option.

C) Frost forming on a car windshield overnight

Frost formation involves water vapor freezing into ice, which is a process that releases heat energy into the air. This exothermic reaction indicates that energy is not absorbed but released, making this choice incorrect.

D) Polar ice caps producing meltwater

The melting of polar ice caps involves the absorption of heat energy from the environment, which causes solid ice to transition into liquid water. This endothermic process effectively demonstrates the absorption of energy, confirming this option as the correct answer.

Conclusion

The correct answer, D, clearly illustrates the process of energy absorption during the melting of ice. In contrast, options A, B, and C describe processes that release energy or do not involve absorption, thereby failing to meet the criteria of the question. Thus, D stands out as the only correct option regarding energy absorption from the surroundings.
