JEE Main 2017 Physics question
A copper ball of mass g is at a temperature . It is dropped in a copper calorimeter of mass g, filled with g of water at room temperature. Subsequently, the temperature of the system is found to be C. is given by: (Given: room temperature C, specific heat of copper cal gC)
Answer: (3)
Solution
Use the principle of calorimetry — heat lost by the hot ball equals heat gained by the calorimeter and the water. Working in calories,
= + .
