Answer 1

The volume of water at the given temperature and pressure is found by using impressibility factor (Z).

Actual volume (V)=$\frac{mZRT}{P}$

Z is obtained from impressibility chart by using reduced pressure(Pr) and reduced temperature(Pr).

Tr=T/Tc,

Pr=T/Pc

where Tc and Pc are values of temp and pressure at critical point.

the calculation is given in tabular form for all questions
