We have the formula for heat released as,
q = m c (T2 - T1)
where m is the mass, c is the specific heat capacity, T2 is the final temp and T1 is the initial temp.
therefore q = 250*0.0921 * (20.5 - 100 ) = -1830.4875 Calories
The negative sign implies that the heat is released.
This is the required answer.
