By shaking you have created air bubble which expands the molecules inside the bottle.
the pressure will be equal throughout the whole bottle
the pressure will be equal throughout the whole bottle
Basically, the pressure will be the same in all parts of the bottle.
Yes, but try to limit the amount of times that happens.
You have to have a 2 liter bottle. then you need some hot water. Swish the hot water around in the bottle with the lid closed. Then after that light a match and put it in the bottle. Close the lid as soon as possible. then squeeze the bottle for a while and watch. Then soon enough the cloud will form, and if you open the lid after you see the cloud and watch, the cloud will come out the top!!!!! HAVE FUN!!!!!
Many glues will not 'set' till exposed to air, some others are carried or mixed with a solvent that evaporates in air. As long as a container remains closed,these glues remain liquid. After using such glue, it's a good idea to squeeze the air out of the tube or bottle if possible.
The ullage is the empty space in a closed bottle. So in a bottle of water, the ullage is between the surface of the water and the bottom of the bottle cap.
the pressure will increase.
Glue doesn't stick to the bottle because, in order for glue to become sticky it has to dry. There's no air circulation in a closed bottle so glue can't dry. If you're thinking, "But what if I leave the glue bottle open! Why doesn't it dry?" It's because there is a lot of glue in the bottle. Not just a thin layer. Just like when you're glueing something and you're not supposed to use that much glue because it won't dry.
Because the substance inside the bottle is highly volatile and can be lost by evaporation if the bottle is not closed.
Not much will happen if you put a glass bottle containing teaspoonful of water in it in the sun with its lid closed. It might evaporate.
