At what temperature does water freeze?
Scenario:
A quantity of water, perhaps in a glass. It's inside one of those imaginary environments, zero energy transfer with the outside world, isolated. The environment has an atmosphere, at exactly zero degrees celsius. [side question: is all the water in the air gone? condensed? just to check. but it's not important to me]
So this glass of water is at zero degrees too. yeah. But it's a glass of water, in liquid form. Everything is at exactly zero degrees.
Question:
Will the water freeze?
[I'm serious]

zero degrees celsius, is it?
