Why is the freezer more frozen after not shutting it properly?

790 viewsOtherPhysics

Basically the title: If I leave the freezer door slightly open it seems to be “more frozen” than before – big chunks of ice on everything, stuff frozen together. Why is that? The food can go bad in this state but it LOOKS colder (I know this is stupid). In my mind it should just melt and warm up 🤷🏻‍♀️

We cannot observe cold directly. What you can see is ice. Ice is formed when water freezes, so there must be water present. When you open the freezer there are warm water particles in the air that move into the freezer, meet the cold air and other objects, and then freezes, being removed from the air and sticking to the surfaces. So, while it isn’t actually getting colder, and instead getting warmer somewhat, the visible indicators of coldness are becoming more apparent.

If you left the door open long enough, you would notice it starting to thaw.
