Because there is humidity going in every time you open the freezer. Inside the freezer humidity is at 0% because all water is frozen, so every time you open it, more water gets in. That's the reason freezers tend to get ice.I don't know how water gets in it other than the Naphtha is just Naphtha so I don't know how the water is getting in it
As @blig-blug alludes, the water comes in as vapour every time you open the freezer door. Some of this vapour can condense (or resublime) directly as ice on the surface of the naphtha, whereupon it promptly sinks due to being denser than naphtha. Ice will also form around the edges of your dish but that will stay where it is until it melts.would there be any other reason to put a lid on it with that heat water from getting in it I don't know how water gets in it other than the Naphtha is just Naphtha so I don't know how the water is getting in it
