Eli5: Why can a thermal flask keep items cold for 24 hours, but only hot for 12 hours.
In: Physics
I fill my new thermal flask up with water before bed, as I’m filling it up I remember little info graphic that was on the packaging about the 24/12 hour thing and I start thinking about it for a while as I get ready for bed and come to the loose conclusion that it must be something to do with hot things being really hot and cold things being slightly cool… then something else fills my mind and the chances I’ll look it up dwindle towards zero. I get into bed and do my usual browse through Reddit, and I stumble upon this question and the correct answer. What a universe.
