Question
If 42.15 grams of ice at 0 deg * C was placed in 450 grams of water at 24.2 deg * C and after a given amount of time when all the ice has melted the final temperature is 15.7C calculate the Molar Heat of Fusion for water based on the experimental values.
Expert Solution
Step 1

As per the law of conservation of energy, the heat lost by water is equal to the heat gained by Ice.

Ice uses the gained heat for the following two processes.

(i) Phase change of Ice from solid to liquid (water)

(ii) Raise of temperature of the water produced in (i) from 0oC to the final temperature i:e 15.7oC.
