Only in certain types of electronics devices and you won't see it directly as contact with the water in air destroys its electronic properties, so germanium devices are hermetically sealed in either glass or metal.
Probably it was not sealed all the way or had holes. Another reason is that it wasn't in there that long or it was supadupa Mouse!
To not let the gas come out ( His Expirement )
The outside air pressure dents the tin. The water or air inside a sealed metal container will contract when cooled from the outside (by conduction through the can). When it was sealed, the pressure on the inside was the same as on the outside. But the contraction reduces the pressure on the inside, causing the external air pressure to squeeze the can, and possibly cave it in. This is widely demonstrated in another experiment using dry ice. A sealed gasoline can of about a gallon (4 liters) is placed on a dry-ice bed and cooled until the outside air pressure crushes the can.
the temperature of gas changes (APEX) :)
I have several sealed boxes of capules and sealed bottles of InVigoral. Please contact cdschewe@yahoo.com.
No, hermetically sealed containers are airtight and should prevent entry of cockroaches or any other pests. Cockroaches require oxygen to survive, so without any air inside the container, they wouldn't be able to survive.
2 weeks
Yes, a large sprig of Elodea and a snail sealed in a tank will survive for several weeks on a sunny window sill. Just make there is plenty of water and food for the snail.
Only Jews were sent to the Warsaw Ghetto. Everyone was ordered out of the area before it was sealed off from the surrounding area.
by providing it with oxygen, water and sunlight despite it being in a seal container will ensure its survival.
A plant, because it can use photosynthesis to make food and still survive.
Most cooked foods that are in sealed packages, However customs frowns heavily upon any one trying to pull a swifty in relatin to importing untreated bio materials.
To do that it would have to have CBRN protection levels i.e. be sealed from CBRN threats. Older tanks wouldn't survive by a longshot, newer tanks might be able to, depends on model.
You should be able to use Spic and Span on any type of sealed wood flooring. If the wood is untreated, or unsealed, it may cause some marring or staining. Always test first.
Cockroaches can survive up to a month without food, but they need water to live. In a sealed plastic jar, they may survive for a few weeks if there is enough moisture inside. However, lack of food and overcrowding will eventually lead to death.
Most survived. There was a ghetto but Jews didn't have tolive there and it was not sealed off. At the time Shanghai was under Japanese occupation, and the Japanese were completely bewildered by European antisemitism.
