"At 0 degrees on this scale, water is in solid form but not at its absolute freezing point."

What the heck does this mean? I don't know what an "absolute freezing point" is, but I know that water is in solid form at 0 K, 0 C, and 0 F. I Googled "absolute freezing point of water" and got:

"The absolute freezing point of water is 0 degrees Celsius, which is equal to 273 Kelvin (K) on the absolute scale."

So, I guess the correct answers are Kelvin and Fahrenheit, because water is in solid form at those temperatures but they aren't the absolute freezing point. The answer listed as correct is the only one that isn't correct because 0 C is the absolute freezing point of water. (Again, whatever that means.)

Water can also exist as a supercooled liquid, so it isn't guaranteed to be a solid at 0C or 0F. Pure water can exist in liquid form down to around -40C before homogeneous nucleation occurs.

I'm with you on this. As written, I think a case could be made for the correct answer being either Kelvin or Fahrenheit, but definitely not Celsius.

I'm wondering if the quiz writer accidentally got the question backwards?

Also Celsius is definitely used in scientific calculations!

If you're talking about the temperature of the universe, sure it's Kelvin - but if we're talking about chemisty, or the climate or the human body, we would use Celsius. I feel like this quizmaster has forgotten doing science at school.

I'm sorry the question was not clear. I'll think of a new one and update the quiz
