Mist are very tiny droplets of condensed water vapor. The water droplets are so small and light that they do not have enough mass to fall on the Earth. As a result they float in the air.
All the noble gases have solid forms that are denser than their liquid forms, so no, the liquid form is not denser than the solid form of Xe.
Solid, liquid and gas are "states" of matter.
Energy comes in many different forms, but not usually in a form that you can say that it sinks or floats.
It evaporates.
That is called a meniscus
frost
Natural gas (out of the ground) that has been compressed until it forms a liquid.
Mostly, we call that water, "Dew".
Liquid rock is called magma when it is underground and lava when it is above ground.
Water Vaper forms when liquid water evaporates.
Sleet forms when it hits the ground
A liquid.
It depends on the type of liquid, though this transition is known as the boiling point (same as when a liquid forms a vapour).
liquid
When a solid forms from a liquid mixture, that is a precipitate, unless the liquid is in the process of freezing, in which case it is a phase change.
it is called condensation. For instance when water evaporates from the ground, it goes up into the sky. Then in the sky it forms clouds. It then rains or precipitates... hope this helped.
No, solid O2 will not float on liquid O2 at all. There are several different phases of solid oxygen, depending on the conditions under which it is formed. But all of them are more dense than the liquid form, even near its freezing point (where it is most dense). None will come close to floating. Liquid oxygen has a density of about 1.141 grams/ml or so, and the solid forms have densities in the area of 1.4 grams/ml or so. Very few substances have a solid phase that floats on its liquid phase. Water is almost miraculous in this physical phenomenon. If ice did not float on water, earth's oceans would freeze solid within a few thousand years (or less).
