Answer: Thus 663 J of heat is released when 27.6 g cools from 83.1 °C to 55.6 °C
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 = ?
m = mass of substance = 27.6 g
C = specific heat capacity =
Initial temperature= =
Final temperature = =
Change in temperature ,
Putting in the values, we get:
As the value of q is negative, it means the heat has been released and it is 663J
