A hot metal bolt of mass 0.06 kg and specific heat capacity 899 J/kg°C is dropped into a calorimeter containing 0.16 kg water at 20°C. The bolt and water reach a final temperature of 25°C.What is the initial temperature of the bolt?
When 1 kg of gold bar of specific heat capacity 129 J/kg°C at 100°C is dropped into 1 kg of water at 25°C, the resulting temperature is:
27°C
75°C
100°C
None of the above
