Using the appropriate tables, determine the change in specific entropy between the specified states, in Bt$($u$)/($l$)$b$*\backslash$deg R$.$

$($a$)$ water, p$\_(1)=10$lb$($f$)/($i$)$n$^(2),$ saturated vapor; p$\_(2)=500$lb$($f$)/($i$)$n$^(2),$T$\_(2)=1000\backslash$deg F$.$

$($b$)$ ammonia, p$\_(1)=140$lb$($f$)/($i$)$n$^(2),$T$\_(1)=160\backslash$deg F;T$\_(2)=-10\backslash$deg F$,$h$\_(2)=345$Bt$($u$)/($l$)$b$.$

$($c$)$ air as an ideal gas, T$\_(1)=80\backslash$deg F$,$p$\_(1)=1$atm;T$\_(2)=340\backslash$deg F$,$p$=5$atm.

Part A

For case $($a$),$ determine the change in specific entropy between the specified states, in Bt$($u$)/($l$)$b $*\backslash$deg R$.$

Case $($a$)$: water, p$\_(1)=10$lb$($f$)/($i$)$n$.^(2),$ saturated vapor; p$\_(2)=500$lb$($f$)/($i$)$n$.^(2),$T$\_(2)=1000\backslash$deg F$.$

$\backslash$Delta s$=$
