You have some serious problems in this post. What's with the steel being added? Surely you mean steam. And when the "steel" was passed into the mixture and temperature (what); i.e., stayed the same, rose by 20 C, decreased by 20 C.
Is that heat capacity of steel or heat capacity of steam?
a copper calorimeter of mass 150g was half filled with water of 300g and temperature 0c. 5g of ice at oc was added to the content, later some quantity of steel was passed into the mixture and temperature by 20c. calculate the quantities of steel added if the latent heat of vapourization of steel is 2.6*10^6jkg specific heat capacity of copper is 400jkgk1
