A gas is a compressible fluid. Not only will a gas conform to the shape of its container but it will also expand to fill the container. In a gas, the molecules have enough kinetic energy so that the effect of intermolecular forces is small (or zero for an ideal gas), and the typical distance between neighboring molecules is much greater than ...
For an example, see Ice § Phases. Liquid: A mostly non-compressible fluid. Able to conform to the shape of its container but retains a (nearly) constant volume independent of pressure. Gas: A compressible fluid. Not only will a gas take the shape of its container but it will also expand to fill the container.
Ice nucleation mechanisms describe four modes that are responsible for the formation of primary ice crystals in the atmosphere. [clarification needed]An ice nucleus, also known as an ice nucleating particle (INP), is a particle which acts as the nucleus for the formation of an ice crystal in the atmosphere.
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
So a collection of enough Bose particles in thermal equilibrium will mostly be in the ground state, with only a few in any excited state, no matter how small the energy difference. Consider now a gas of particles, which can be in different momentum states labeled | . If the number of particles is less than the number of thermally accessible ...
Virtually all ice in the biosphere is ice I h (pronounced: ice one h, also known as ice-phase-one). Ice I h exhibits many peculiar properties that are relevant to the existence of life and regulation of global climate. [138] For instance, its density is lower than that of liquid water.
We propose that matter is not made of particles or waves, as was long thought, but – more fundamenta Fragments of energy – not waves or particles – may be the fundamental building blocks of ...
All known fermions except neutrinos, are also Dirac fermions; that is, each known fermion has its own distinct antiparticle. It is not known whether the neutrino is a Dirac fermion or a Majorana fermion. [4] Fermions are the basic building blocks of all matter. They are classified according to whether they interact via the strong interaction or ...
