A copper vessel of mass 1000g contains 500g of water at 50C. An ice cube of mass 100g at temperature -30C is dropped into the vessel.
a)Does the ice melt? Explain in a few words how you reached to your answer.
b) What is the final temperature?
c) Repeat part b if at the same time as dropping in the ice cube, wealso drop in a 200g piece of glass at a temperature of 110C.
Specific heats in cal/g.C
Ice=0.5 water=1.0 Copper=0.1 Glass=0.2
Latent heat of water: Vapourization =540cal/g Fusion=80cal/g
