Can Hot Water Freeze Before Cold Water? The Mpemba Effect

Here is a link to a fascinating post on this subject from earlier this year at Skulls in the Stars. The effect has apparently been observed for millenia (the post contains a reference by Aristotle!), but the conditions under which it occurs and the scientific explanation for the Mpemba effect are still unclear.

Interested experimenters with room in their freezers (Dr. SkySkull mentions that his freezer is full to the brim, on account that he’s married … I’m afraid I’m in the same boat) might like to explore this phenomenon.

About Santo D'Agostino

I have taught mathematics and physics since the mid 1980s. I have also been a textbook writer/editor since then. Currently I am working independently on a number of writing and education projects while teaching physics at my local university. I love math and physics, and love teaching and writing about them. My blog also discusses education, science, environment, etc. https://qedinsight.wordpress.com Further resources, and online tutoring, can be found at my other site http://www.qedinfinity.com
