Use the steam tables and chart:

$($a$)$ What is the enthalpy change needed to change $3lbs$ of liquid water at $32F$ to steam at $1$atm and $300F?$

$($b$)$ What is the enthalpy change needed to heat $3lbs$ of water from $60a$ and $32F$ to steam at $1$atm and $300F?$

$($c$)$ What is the enthalpy change needed to heat $1lb$ of water at $60$ psia and $40F$ to steam at $300F$ and $60$ psia?
