When 0. 25 g of the organic compound naphthalene are burned in a bomb calorimeter, the temperature of the water in the calorimet
Korvikt [17]

-2.5089 kJ is the amount of heat is released by the combustion of the naphthalene.

<h3>How we calculate the released heat?</h3>

Released amount of heat is calculated by using the below formula:

Q = -mcΔT, where

m = mass of naphthalene = 0.25g

c = specific heat of calorimeter = 4.13 kJ/°C

ΔT = change in temperature = 26.43°C - 24°C = 2.43°C

Putting all these values in the above equation, we get

Q = - (0.25 × 4.13 × 2.43) = - 2.5089 kJ

Hence, - 2.5089 kJ heat is released.
