I might be alone on this but the freezing point of water is almost irrelevant in daily life. Any precipitation from 30°F (-1°C) to 35°F (1.5°C) results in some mix of snow/slush. Less than that and it’s snow/ice.

However if you live somewhere where they use salt as a de-icer, knowing the freezing point of saltwater (0°F, -17.7°C) is very, very important.

I know you said no voice-reading-text and wanted personality, but for my money nothing is better background listening than History of English. You can listen to the whole narrative of an episode or just pick up some cool etymology here and there.
