Give the order of magnitude of nuclear mass density and average atomic mass density. Compare these densities with the typical mass density of solids, liquids and gases (at oridnary temperature and pressure). |
| Answer» Solution :Nuclear mass DENSITY is of the order of `10^(17)KG m^-3`. This is `10^(13)` to `10^(14)` times the average atomic mass density, which is of the order of `10^3` to `10^4kgm^-3`. Typical mass densities of solids and LIQUIDS are of the same order as the atomic mass densities. This is because the atoms are tightly packed in these phases. The typical densities of GASES at S.T.P. are of the order of `10^-1kgm^-3` to `1kgm^-3`. | |
