Expansion / Contraction of Ice
Fill in these blanks:
Density of liquid water at +4°C:___
Density of liquid water at 0°C: ___
Density of ice at 0°C:___
Ice is much less dense. Is the 0.01% volume increase from 4°C to 0°C liquid really enough to burst pipes? Not in most countries with adequate plumbing codes. A quick hoop stress calculation shows this.
