Question

An open insulated calorimeter of water equivalent 20 g holds 100 g water and 50 g ice at 0°C. Pass 100 g steam at 10 0 ∘ C through it. cw = 1 cal / ( g ∘ C ) , Lf = 80 , Lv = 540 cal / g . Final retained liquid mass is closest to:

TestHub · Accepted Answer

Heat needed = 50 ( 80 ) + ( 100 + 50 + 20 ) ( 100 ) = 21000 cal. Steam condensed = 21000/540 = 38.8889 g . Retained mass = 150 + 38.8889 = 188.8889 g at 100°C; excess steam exits. A.
