Short answer: Glass is usually air-tight, so you can't breathe.
Long answer: The human body needs a more or less constant percentage of oxygen in the air so that the lungs can distribute enough through the body.
Inside of a sealed container, a living human is using up the oxygen they already have, but no more is being created or allowed through, so the oxygen percentage goes down. Once it hits a certain point, the body can no longer get what it needs from the air and the person will die of asphyxiation.
No. Watch what happens with talcum powder. When the particles between the solid are more cohesive than the attraction to water molecules, they will not be "wetted" and remain floating.
the answer is false Permanent magnets will hold their magnetism for a long period of time. Electromagnets will only remain magnetic as long as current is flowing through them.
No, the cremated remains of a person, their ashes, do not change over time. The ashes are what is left of the crushed bones and will remain as that.
During sleep, the medulla oblongata controls sleep and arousal monitoring sensors to the cortex and other parts of the body. There are cholinergic neurons in the medulla oblongata that remain active during REM sleep. When a person experiences sleep walking, these neurons become inactive which causes a person to sleep while in action.
in a one word answer it is an "emullsion", an emulsion (NOT SURE OF SPELLING!) is a mixture that contains things that cannot be disolved into a perfect solution by a single solvent but can be mixed into a liquid so that they components remain evenly spread. i hope this answers the question.
The question cannot be answered because it is based on a false premise: the number of elements does NOT remain fixed.
The chemical structure of water remain unchanged.
The chemical nature of water remain unchanged.
In a container the volume remain constant but the pressure increase.
Because of Habeus Corpus, a person cannot be held in jail without a reason.
A solid will remain the same volume and shape A liquid will remain the same volume but change shape to its container A gas will expand its volume to fill its container entirely
The chemical formula of water molecule (H2O) remain unchanged.
Salt is not evaporated with water and remain as a residue.
You cannot make it not come so often,it would be hard to make it stop! If you are getting to the age of period though,don't worry! its nothing to be scared of,I am only 10 so i do not EXACTLY know but i know you cannot stop it anyhow so just remain calm,its not going to kill you!
Copper sulfate crystals remain in the container.
I believe the standard shelf life of petrol is around 6weeks in a normal fuel container.
Chemically any difference exist.
