You have $4kg$ of $H2O$ at $500C$ and $\frac{20}{b}ar$ in a constant pressure vessel $($e$.$g$.$ it has a piston that can move$)$

a$)$ What phase is the $H2O$ in and what is the initial volume of the $H2O?$

b$)$ You now remove $2000kJ$ of heat from the $H2O$ by spraying cold water on the outside of the vessel. Calculate the new temperature and volume of the $H2O.$

c$)$ You now remove another $3000kJ$ of heat from the $H2O($total of $5000kJ$ of heat removed from the original state$).$ Again, calculate the new temperature and volume of the $H2O.$

d$)$ How much more heat $($after step c$)$ do you have to remove from the $H2O$ to have it reach a temperature of $200C?$
