Equation of state of an ideal gas is

What is the equation of state of an ideal gas ? Why is it so called ?

In the equation of state of an ideal gas PV =nRT , the value of the universal gas constant is not correct :

In the equation of state of an ideal gas PV = nRT, the value of universal gas constant would depend only on :

What is the equation of state of an ideal gas for n moles ?

In van der Waal's equation of state for a non ideal gas the term that accounts for i9ntermolecular forces is:

Find the pressure of saturated vapour as a function of temperature p(tau) if a temperature T_0 its pressure equals p_0 . Assume that : the specific latent heat of vaporization q is independent of T , the specific volume of liquid is negligible as compared to that of vapour, saturated vapour obeys the equation of state for an ideal gas. Investigate under what conditions these assumptions are permissible.

In van der Waal's equation of state for non ideal gas, the term which accounts for the intermolecular forces is
