A jet delivering 0.44g of dry steam per second, at 100oC is directed on to crushed ice at 0.0oC contained in an unlagged copper can which has a hole in the base. 4.44g of water at 0.0oC flow out of the hole per second.
(i) How many joules of heat are given out per second by condensing steam and cooling to 0.0oC of water formed?(Latent heat of vaporization of steam = 2.26 x 106JKg-1,c for water = 4200JKg-1K-1)
(ii) How much heat is taken in per second by the ice which melts?
(iii) Suggest why these amounts above are different
