WebSo if you were looking for the strange effect of the hot water freezing sooner, you might test with the temperature just a little below 0°C, say -5°C. That's because dissolved gases (more likely to be in cold water) lower the freezing point, and that's very noticeable if the freezer temperature is close to the freezing point.
