Temperature of 100 g of water in a thermoflask remains fixed for a pretty long time at 50^(@)C . An equal mass of sand at 20^(@)C is poured in the flask and shaken for some time so that the temperature of the mixture is 40^(@) . Now the experiment is repeated with 100g of a liquid at 50^(@) C and an equal amount of sand at 20^(@)C when the temperature of the mixture is found to be 30^(@)C The specific heat of the liquid (in KJ//KgxK) is

Two liquids are at temperatures 20^@C and 40^@C . When same mass of both of them is mixed, the temperature of the mixture is 32^@C . What is the ratio of their specific heats?

When a hot liquid is mixed with a cold liquid, the temperature of the mixture

Equal masses of three liquids A,B and C are taken. Their initial temperature are 10^@C,25^@C and 40^@C respectively. When A and B are mixed the temperature of the mixutre is 19^@C . When B and C are mixed, the temperature of the mixture is 35^@C . Find the temperature if all three are mixed.

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.
