Gas Law

1.a) state the assumption associated with the model used to develop the Ideal Gas Law

b) hence or otherwise describe under which physical conditions does the ideal gas law applies

2. Explain why hydrogen which has one electron in its lowest state, should in principle be a metallic conductor in its solid state whereas helium which has two electrons in its lowest energy state should be an insulator.

Answer 1.

The ideal gas equation also called ideal gas law can be written as under:

PV = nRT

This equation interrelates 4 quantities, pressure, volume, temperature and number of moles (n).
This equation is applicable only in the cases where Temperature is AROUND room temperature and pressure is AROUND 1 atmosphere. The word around here means they are not exactly 1 atmosphere or room temperature. If the pressure and temperature vary from these values ...
