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 75°C. T is given by :
(Given : room temperature = 30°C, specific heat of copper = 0.1 cal/gm°C)
  • a)
    1250°C
  • b)
    825°C
  • c)
    800°C
  • d)
    885°C
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
A copper ball of mass 100 gm is at a temperature T.It is dropped in a ...
100 × 0.1 × (t – 75) = 100 × 0.1 × 45 + 170 × 1 × 45
10t – 750 = 450 + 7650
10t = 1200 + 7650
10t = 8850
t = 885°C
