Hypothetically, if you had a gas made of really heavy atoms/molecules (although it's unlikely that they would be stable at the kind of Uranium-heavy I'm thinking of, let's say that hypothetically they are) in a liquid made of really really light molecules or atoms (e.g hydrogen), and say that temperature isn't going to change the given states of the elements (very very hypothetically), and so they can exist in the states they need to together, could the bubbles go down? Or would the relative densities make the masses of the atoms and molecules irrelevant?
When I open a new jar of marmalade the contents are a nice,
semi-solid, homogenous mass with a smooth surface, however old the jar
is. Yet when I make a spoonful-sized hole in the flat surface to remove
some marmalade, the next time I open the jar a couple of days later, the
hole has started to fill with a syrupy liquid. What is it about
breaking the surface of the marmalade that sets this process in motion?
It continues until the jar is empty.
Water molecules are slightly polarised so they should line up in a strong electric field. I was always taught that they form hexagonal structures when they freeze though. Which of these effects is more powerful? Does the water freeze with a different structure? What happens if I subsequently remove the electric field?
By trapped i mean, for example, enclosed in an otherwise solid metal cube with no air spaces. would it stay a supercooled liquid or become a compacted solid, or some medium in between?
On looking at windows and car windscreens when it rains, I have noticed that raindrops tend to follow the previous paths of other drips when falling down the glass surface. Why is this?
