Q. A sample of 10gm of steam at 100oC with 6gm ice at 0oC is kept inside a calorimeter initially. Find the amount of steam in gm left? (LFusion​=80cal/gm,LVaporization​=540cal/gm,Specificheatcapacity=1cal/(gm)oC)

fusion6×80​​+raisetemp6×1×(100−0)​​=condensationx×540​​ ∴x=2gm⇒leftsteam=8gm

$f u s i o n 6 \times 80 + r ai se t e m p 6 \times 1 \times (100 - 0) = co n d e n s a t i o n x \times 540$
$∴ x = 2 g m \Rightarrow l e f t s t e am = 8 g m$
