A piece of copper of mass 40g at 200°C is placed in a copper calorimeter of mass 60g containing 50g of water at 25°C. Ignoring heat losses, what will be the final temperature of the mixture. (Specific heat capacity of copper= 0.4J/g/K, specific heat capacity of water= 4.2J/g/K )?Please show workings. |

Answer» final temperature be Considering the piece of copper,MASS, specific heat capacity, initial temperature, [Note: in case of considering temperature difference it's not required to CONVERT the temperatures from to or vice versa.]Then the heat of copper,Considering copper calorimeter,mass, specific heat capacity, initial temperature, Then its heat,Considering WATER,mass, specific heat capacity, initial temperature, Then its heat,By energy conservation, the sum of all these energies should be ZERO as there were no heat energy change before the process, i.e., |
