The bolt and water reach a final temperature of 25cwhat is


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

What is the heat required in kilocalories to convert 2 kg of ice at 0°C completely into steam at 100°C?

How many kg of ice needs to be added to 1.31 kg of water at 64.9°C to cool the water to 14.9°C when the Latent heat of ice = 80 kcal/kg?
