consider a copper of mass 50kg at temperature 10⁰c and a copper calorimeter of 15kg with water to weigh 40kg when heat energy is supplied to the calorimeter until the temperature reaches 50⁰c find the s.h.c of copper (s.h.c of water =4200/kg.k and calorimeter is 400j/kgk)initial temperature of calorimeter =54⁰c
