to get the heat released or absorbed,

Q = mc(T2-T1)

where

m = mass of substance (units in g)

c = specific heat capacity (units in J/g-K)

T2 = final temperature

T1 = initial temperature

**note: if Q is (-), heat is released and if (+), heat is absorbed

for water c = 4.184 J/g-K

substituting,

Q = 100*4.184*(308-288)

Q = 8368 J

hope this helps~ :)
