The article states that hot water can freeze faster than cold water, which means, correct if I'm wrong that that result is subject to other conditions. Hot water freezes faster than cold water at first.

Sorry, there are more things out there in reality than you can dream of in your limited hypothesis. Maybe you need to test it.

Or if you're scared of that try reading
