Water of mass 200 g and temperature 30^(@)C is taken in a copper calorimeter of mass 50g and temperature 30^(@)C . A copper sphere of mass 100g and temperature 100^(@)C is released into it. What will be the maximum temperature of the mixture ? [ c ( water = 1 cal //g.^(@) C , c ( copper ) = 0.1 cal//g.^(@)C ]

50 g of copper is heated to increase its temperature by 10^@C . If the same quantity of heat is given to 10g of water, the rise in its temperature is (specific heat of copper =420J//kg^(@)//C )

In an experiment to determine the specific heat of aluminium, piece of aluminimum weighing 500 g is heated to 100 .^(@) C . It is then quickly transferred into a copper calorimeter of mass 500 g containing 300g of water at 30 .^(@) C . The final temperature of the mixture is found to be 46.8 .^(@) c . If specific heat of copper is 0.093 cal g^-1 .^(@) C^-1 , then the specific heat aluminium is.
