Latent Heat

Q:
Recently saw a experiment where they were monitoring the temperature of water as it froze. The results seemed to show that just after the water in the container reached 32 and ice formed that the temp. actually warmed a bit. I assume its is because energy was released as the water changed states. Is this correct?

A:
Yes, as the ice forms heat is released. Typically the liquid can get a bit below the freezing point ("supercooled") before the ice starts to form. Then the heat released as it forms brings the temperature up to the freezing point.
