Answer: The amount of heat released is 42739 Joules
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
[tex]Q=m\times c\times \Delta T[/tex]
Q = Heat released =?
c = heat capacity of granite = [tex]0.790J/g^0C[/tex]
Initial temperature = [tex]T_i[/tex] = [tex]41.2^0C[/tex]
Final temperature of the calorimeter = [tex]T_f[/tex] = [tex]-12.9^0C[/tex]
Change in temperature ,[tex]\Delta T=T_f-T_i=(-12.9-41.2)^0C=-54.1^0C[/tex]
Putting in the values, we get:
[tex]Q=1000g\times 0.790J/g^0C\times -54.1^0C=-42739J[/tex]
As heat comes out to be negative, that means the heat has been released and the amount of heat released is 42739 Joules
