So yes, that is a pretty massive thing, especially happening over a lifetime.
- lurquer 8y agoThe freezing point of water creates a discontinuity in the effects of temperature change. That is, a ten degree swing that results in water freezing (or melting) for most of the year is far different than than a ten degree swing in a range far above (or below) 32 degrees.
