Final answer:
The cup of room-temperature water freezing violates the Second Law of Thermodynamics.
Explanation:
The cup of room-temperature water spontaneously freezing violates the Second Law of Thermodynamics. This is because the Second Law states that heat cannot transfer energy spontaneously from a colder to a hotter object. In this case, the water would need to give off heat to its surroundings, causing an increase in entropy, which goes against the law.
