Making use of the values of the critical parameters of water ( 35.5) check whether those parameters satisfy the ideal gas law. Explain the result.

Explanation

`(R)/(M) rho _(er)T_(r)=9.8xx10^(7)` Pa, at the same time `p_(er)=218` atm `=2.2xx10^(7)Pa`.
Hence the Mendeleev-Clapeyron equation is inapplicable to the critical state. This is because of the large part played in this case by

molecular interactions, which are neglected in the case of an ideal gas.
