# Freezing water in a closed container [duplicate]

We know that density of ice reduces by about 8% during freezing, this means it expands to have little higher volume. But if I fill water in a container (entire volume) which has very low coefficient of thermal expansion at 0 $^\circ$C, will the space constraints stop water from freezing?

Does the space constraint of a cast-iron engine block stop a pure water coolant from freezing? –  DJohnM Dec 19 '13 at 0:12
I worked with a professor who used to do the exploding cast iron ball full of water demo. Energetic and surprising even though you know what is coming. –  dmckee Dec 19 '13 at 4:40

For thermo with no stress/strain you look at the free energy: $$F=U-TS$$ but when you incorperate stress/strain there is an additional term like: $$F=U-TS-\sigma d\epsilon$$ Which incorperates the energy of compressing the solid.
