In fairness latent heat of fusion is surprisingly high.
Actually, I don't think this is quite right. A cube of water 10cm in size is 10 grams. The heat of fusion for water is 333.55 J/gram, and a AA is 14400 Joules. So the energy for the ice cube (which is 4 inches across, in imperial units) is 10 grams * 333.55 J/gram = 3335.5 Joules, which is ~1/4th of the very large ice cube.
- mrguyorama 4y ago>10cm in size What about the other two dimensions? I used an ice cube containing 50ml of water, ie 50 grams. That specific number came from a quora answer where someone measured their own ice cube tray, but they seem to have giant ice cubes. Other sources mention numbers from 20ish ml to that 50ml upper bound, so I'd say the number I calculated is actually double a more reasonable answer. So a middle sized ice cube required the same energy available in an off brand, cheap-o non-alkaline chemistry AA battery. Damn, that's way less of a convenient number.
