My brother and I were talking about how he needed to take his beers out of the freezer because they would burst open. This made me think of something no professor ever addressed... Obviously work is occurring on the beer can, but oxymoronically it's due to the removal of heat energy. The secret I imagine is in the phase change itself, which likely takes its own energy (which would normally be given off as heat) and uses it to expand (do work).
My questions extend on this idea...
What if we replace the beer can with a 5 inch thick steel capsule. Does the capsule prevent the water from freezing because there isn't enough room to expand?
What about if you take even more energy away? Would absolute zero finally break the capsule?
Can a strong enough container simply prevent water from phase changing to a solid altogether, regardless of temperature?
Normally increasing the pressure of a substance will cause it to freeze (in chemistry class my teacher made water boil at room temperature with a vacuum pump removing pressure). With water though, it expands while freezing... So paradoxically if you have water in a strong capsule and keep increasing the pressure (instead of temperature), will the water eventually freeze or simply remain very cold liquid?
