A copper ball of mass 100 gm is at a temperature T. It is dropped in a copper calorimeter of mass 100 gm, filled with 170 gm of water at room temperature. Subsequently, the temperature of the system is found to be 75º C. T is given by: (Given: room temperature = 30ºC, specific heat of copper = 0.1 cal/gmºC)
Text Solution
Verified by ExpertsThe correct answer is:
C
Heat given by cupper ball = Heat taken by water + Heat taken by calorimeter system
(100) (0.1) (T – 75) = (170) (75 – 30) + (100) (0.1) (75 – 30)
10T – 750 = 8100
10T = 8850
T = 885°C
