Answer: The amount of heat released is 42739 Joules
Step-by-step explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q = Heat released =?
c = heat capacity of granite =

Initial temperature =
=

Final temperature of the calorimeter =
=

Change in temperature ,

Putting in the values, we get:

As heat comes out to be negative, that means the heat has been released and the amount of heat released is 42739 Joules
