Question

PLEASE ANSWER QUESTION 2:

1)A calorimeter has aluminum inner cup of mass 120 gram containing 100 ml water at temperature 20 degree Celsius. Brass piece with mass 100 gram is heated to 100 degree Celsius, and then immersed in the calorimeter. Calculate the final temperature of the system. The specific heat of brass is 0.09 cal/(gramXdeg.C) . The additional necessary data are provided in the text.

2)A chunk of 15 gram ice is pulled from a freezer keeping temperature -20 deg. Celsius, and placed in an identical calorimeter as the one described in problem 1. The final temperature of the system is measured to be 8 deg. Celsius. What is the experimental latent heat of fusion of ice?
