Quizplus · Accepted Answer

The freezing point of water at 1 atm pressure is 0°C, which is the same as 32°F or 273.15 K. Choice A is incorrect because 0°F is below the freezing point of water. Choice B is incorrect because 0 K is absolute zero, which cannot be reached in reality. Choice C is incorrect because -273°C is absolute zero, which again cannot be reached in reality. Choice E is incorrect because -32°F is still below the freezing point of water.
