How much heat is released when 27.6 g P C l subscript 3 cools from 83.1 °C to 55.6 °C? (The specific heat of P C l subscript 3 is 0.874 J/g °C).

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
