A $1-m^3$ tank contains $2\mathrm{.}108$ kg of steam at $0\mathrm{.}6$ MPa $.$ The gas constant, the critical pressure, and the

critical temperature of steam are $R=0\mathrm{.}4615$kPa$*\frac{m^3}{k}g*K,T_{cr}=647\mathrm{.}1K,$ and $P_{cr}=22\mathrm{.}06$MPa

$.$ Use data from the steam tables.

Determine the temperature of the steam using the van der Waals equation. $($Round the final answer to three decimal places.$)$

The temperature is

K$.$
