The specific heat capacity of copper is 400j/kg/k. A piece if copper ball of mass 20g at 200 degrees Celcius is placed in a copper calorimeter of mass 60g containing 50g of water at 30degrees Celcius, ignoring heat losses, calculate the final steady temperature of the mixture. (Specific heat capacity of water =4.2j/g/k)
