Explanation:
nice question...
ok solution goes right the way through...
in temp 193°C the volume of gas was 892ml
so for...144°C the volume of gas will be 892/193x144=665.533 or 665.534...(rounded off)...or 665°...(approx)....so got ur answer...
I hope it helps....
please comment if you have any further questions...i will be solving it for u...
