Question

A copper ball of mass 100gm is at a temperature T. It is dropped in a copper calorimeter of mass 100gm,
filled with 170gm of water at room temperature. Subsequently, the temperature of the system is found to
be 75°C. T is given by

a) 1250°C
b) 825°C
c) 800°C
d) 885°C​

Answer 1

$\huge{\underline{\bold{\orange{Answer}}}}$

Final temperature of celomiter and its constant is given as

To= 75°C

⇒ 100×0.1×(75−T)+100×0.1(75−30)+1.70×1×

(75.32)

∴ T=885 °C

Answer 2

Answer:

your answer is d) 885°C
