Themelting pointof a substance is the temperature at which it changes state from solid to liquid at atmospheric pressure; at the melting point, the solid and liquid phases exist in equilibrium. A substance's melting point depends on pressure and is usually specified at standard pressure in refer...

Iron (Fe) - Iron is represented as Fe and has an atomic number of 26. Iron atomic mass is 55.845 u. Know the physical and chemical properties, density, boiling and melting point, along with the uses of Iron on BYJU'S.
As molar mass increases, the number of electrons increases, resulting in: (a) more dipole-dipole interactions. (b) greater dispersion forces. (c) decreases in the boiling point. (d) activation of additional at Does argon or krypton have a higher boiling point? ...
From adsorption isotherms of krypton on graphite measured between 79.24 and 88.46 K in the monolayer domain a two-dimensional triple point of 84.8 ± 0.5 K is determined for this system. Thermodynamic analysis of these isotherms and of t... Y Larher - 《Journal of the Chemical Society》 被引...
Below a coverage of 1 Ar atom per six surface carbon atoms (ρ=1) the onset of this transition occurs at a coverage-independent temperature T=47.9 K. We interpret this point as a critical end point for melting. For coverages 0.94<ρ<1.2 continuous broadening is also observed, but the ...

The positions of the triple point were calculated from the intersection of the extrapolated melting curves and vapour pressure lines. It was found possible to derive a law of corresponding states; the reduction factors to be used could not be based on the parameters of a Lennard-Jones 12-6 ...
The melting temperature of a monolayer adsorbed in the pore is lower than the temperature of the 3D triple point. However, the adsorption of the second layer pushes the temperature of melting of the contact layer up. The two-layer system behaves in a very heterogeneous way, that is, the ...
