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 i
Paul [167]

Answer: Thus 663 J of heat  is released when 27.6 g PCl_3 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=m\times c\times \Delta T

Q = Heat released = ?

m = mass of substance = 27.6 g

C = specific heat capacity = 0.874J/g^0C

Initial temperature= T_i = 83.1^0C

Final temperature  = T_f  = 55.6^0c

Change in temperature ,\Delta T=T_f-T_i=(55.6-83.1)^0C=-27.5^0C

Putting in the values, we get:

Q=27.6g\times 0.874J/g^0C\times -27.5^0C=-663J

As the value of q is negative, it means the heat has been released and it is 663J
