(Solved)
Water of mass 200g at temperature of 60°Cis put in a well lagged copper calorimeter of mass
80g. A piece of ice at 0° C and mass 20g is placed in the calorimeter and the mixture stirred
gently until all the ice melts. The final temperature, T, of the mixture is then measured.
Determine:
i) The heat absorbed by the melting ice at O°C
ii) The heat absorbed by the melted ice (water) to rise to temperature T (answer may be
given in terms of T)
iii) The heat lost by the warm water and the calorimeter (answer may be given in terms of T)
iv) The final temperature of the mixture
