A sphere of aluminium of 0.06 kg placed for sufficient time in a vessel containing boiling water, so that the sphere is at 100°C. It is then immediately transfered a vessel containing 0.25 kg of water at 20°C. The temperature of water rises and attains a steady state at 24°C. Calculate the specific heat capacity of aluminium. (neglect heat loss to vessel and surroundings)
- 870 J kg–1 k–1
- 1024 J kg–1 k–1
- 921 J kg–1 k–1
- 708 J kg–1 k–1
Answer
(C) 921 J kg –1 k –1
