It is also quite possible that you are still working on solving the problem subconsciously.

As a sheepy during my morning commute on the train, not only do I listen to the Beach Boys "Sheep Sounds" ewesing my "BLEATS" but I also do word puzzles !...I have found that when I become stuck on a puzzle and then put it away till the commute home that I can then instantly comBLEAT the once offending puzzle from the morning with ease !I get the same effect. I suspect certain assumptions act as mental blocks pulling WOOL over your eyes, and giving it a rest allows these blocks to evaporate. Looking at the problem anew after a time forces one to reassess what's going on, and often that assessment sees new things that were assumed not there before. Something like that.
Let's say that the fridge interior is kept at 8 °C (281 K), and the air in your kitchen is 24 °C (297 K), so there is a fairly significant difference between the two (otherwise you wouldn't need a fridge!). When you open the door, the air mixes--for the sake of argument let's say that the air inside reaches 22 °C (295 K) by the time you are ready to close it.Experiment time. It seems pretty unlikely that air would warm up to anywhere near room temperature in a box full of cold items. Worst case is an empty fridge: all air and no objects to cool the incoming warm air.
You can. but that's not quite the same thing.Quote from: boredchemistx^6 - 531 x^5 + 117475 x^4 - 13859985 x^3 + 919750924 x^2 - 32549480844 x + 479926006560=0Can't you fit 5 arbitrary numbers to a 5th degree polynomial?
...although it's tougher if you insist that the unknown 6th number must be an integer
...and even tougher if you insist that all coefficients must also be integers!
