An electric immersion heater is inserted into a calorimeter made of copper of mass 15kg and 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°C provided by the meter. then a piece of ice of mass 2kg is added at a temperature of 2°C into the meter and stirred continuously until it reaches the final temp. If the process takes 15mins, find the final temperature of the mixture. assuming negligible heat loss.
[Specific heat capacity of water=. 4200j/kg]
[Latent heat capacity of ice=. 336000kg]
[S.h. c of copper is= 400J/kg]?
