A copper calorimeter of mass 150g was half filled with water of mass 300g at temperature 0°c.5g of ice at 0°c was added to the content, later some quantity of steam was passed into the mixture and temperature rise by 20°c. calculate the quantity of steam added Lv of steam=2•26×10^6 Joule per kilogram
S•H•C of copper=400 joule per Kilogram per kelvin
S•H•C of water=4200 joule per kilogram per kelvin
Lf of ice= 3•36×10^5 joule per kilogram
