The key properties of plasma that depend on the ion size are: 1) Electric conductivity since it depends on Coulomb scattering of electrons on ions and the rate of it scales as the ion charge squared 2) Radiation properties - for fully ionized plasmas the bremsstralung (braking) radiation due to the Coulomn scattering of electrons on ions strongly grows with ...

Wood can only be solid because it's a very specific arrangement of atoms. If you liquified or vaporized all the elements in it, they wouldn't be wood. You also can't have liquid crystals, unless you count liquid crystals. Or a liquid computer.

H2O at 0°C is Ice. There is a considerable gap between Ice and Water. After 0°C if you increase the temperature by 0.1°C, that is at 273.1K the equlibrium state occures. This state is called the 'Triple point of water'. This is where water, ice and surprisingly water vapour. After this state if you increase the temp by any amount H20 becomes water. Hope this ...

At the transition point between two phases, both states are thermodynamically (meta)stable. The actual composition, however, is kinetically determined and will depend on the history of how you got to 0$^\circ$C and how long you wait. For instance, if pure water (no impurities and in a container that does not induce heterogeneous nucleation) is cooled slowly ...

I'm assuming 1 atm pressure. It will be a mix of solid and liquid. It takes a certain amount of thermal energy to change the state of water. Until that amount of energy is reached, it will be a mixture of solid and liquid, both at 0°C. With more energy, a higher portion will be water. Once all of it is liquid, any further energy addition will raise its ...

You need more information to tell the state. Actually, exactly two more values, the pressure and the volume. With these three you have a fixed point in the phase diagram: But even if you have a fixed point in the diagram, you can still reach a two-phase sitation. Then e.g. water and ice exists at the same time in fitting fractions of the total mass. What ...

Yes. Plasma consists of ionized matter. Which contains cathode rays (electrons) which are indipendant of the matter and positive rays ( nucleii) which depen on the matter ionized. So as plasma is a mixture of both it shows a significant physical difference. Eg: Density, Charge/Mass ratio, Effect due to Electro-magnetic fields

Most substances can perform a large number of phase transitions. There are even different kinds of phase transitions and sometimes two phases can be connected by more than one process. The quantities governing what phase transition occurs are so-called state variables; temperature and pressure are the best known representatives, but e.g. magnetic fields can ...

Like is gold plasma more dense than iron's? If you mean mass density, then for the same ion number density and charge state (assuming quasi-neutrality) the gold plasma would have a higher mass density than that of iron. If you mean number density, then that would depend upon how the plasma was formed and under what conditions it currently exists (i.e., ...

When a substance skips the liquid phase and deposits as a solid directly from its gas phase, it's called deposition. When it evaporates directly from solid to gas it's called sublimation. The key to this happening is the equilibrium vapor pressure of the substance, which is the pressure exerted by its gas phase when it's in thermodynamic equilibrium with ...

Iodine - solid to vapor when heated under normal condition. In this context the word you need to search for is "sublimation"

In gases, under normal conditions, the average distance between molecules is large compared to size of the molecules so the molecules spend most of their time far apart. Interactions between molecules, or at least strong interactions between molecules, tend to be short range. This means that interactions between molecules don't have much effect on the ...
