Q. Supercooled water at -10C can spontaneously warm to 0C in a perfectly insulated container. This is possible because
a. supercooled materials do not obey energy conservation laws
b. supercooled water needs less energy for change of temperature than ordinary water
c. a small amount of energy is given to the surroundings
d. some of the water freezes and this provides energy
e. ice is unusual in that it is less dense than liquid water
From a very reliable source....I didn't even know what supercooled water was before encountering this problem. Still, I don't get it. Anyone?
