$16.$ A heat engine is proposed which is to operate between $2000$C and $500$C with an efficiency of

$35$percent.

$($a$)$ The Temperatures in Kelvin are $473$K and $323$K respectively $($T$,$ F$)$

$($b$)$ The maximum efficiency using the given temperatures are $32$ percent $($T$,$ F$)$

$($c$)$ Will the engine perform as predicted; that is will it have an efficiency of $35$percent $($yes$,$

No$)$
