148395 A closed copper vessel contains water equal to half of its volume. When the temperature of the vessel is raised to $447^{\circ} \mathrm{C}$. The pressure of steam in the vessel is: (Treat steam as an ideal gas. Universal gas constant $=8310 \mathrm{~J} / \mathrm{mol}-\mathrm{K}$, moledensity of water is $1000 \mathrm{~kg} / \mathrm{m}^{3}$, molecular weight of water $=18$ )
