Water expands when it freezes. Ice takes up more space than water. Where do I find the formula?
Given this unbearable heat, I want to take some plastic water bottles (liter size) and fill them with water and stick them in the freezer.
I know I shouldn’t fill them all the way to the top because the plastic will split and burst as the ice expands.
What is the formula I should use? Where do I find the expansion rate of water? (Or said another way – should I only put 800 ml into a liter bottle? Is that conservative enough?)
