An electric immersion heater is inserted into a calorimeter made of copper of mass 15kg and a current of 0.1A. A voltage of 1.6v was passed through the metre and a water of mass 40kg was put into the calorimeter at a temperature of 30 deg. Celsius provided by the metre. Then a piece of ice of mass 2kg is added at a temperature of 2 deg. Celsius into the metre and stirred continuously until it reaches the final temperature of?. If this process takes 15mins, find the temperature of the mixture assuming negligible heat loss. (shc of water=4200j/kgk, shc of copper=400j/kgk, latent heat of ice=336000j/kg)?
