A jet delivering 0.44g of dry steam per second, at 100^oC is directed on to crushed ice at 0.0^oC contained in an unlagged copper can which has a hole in the base. 4.44g of water at 0.0^oC flow out of the hole per second.
(i) How many joules of heat are given out per second by condensing steam and cooling to 0.0^oC 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

  

Answers

---

(iii) - Heat is absorbed from the surrounding since the can is unlagged;
