How many joules of heat are lost by 1000g of granite as it cools from 41.2 Celsius to -12.9 Celsius?

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.

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

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
