This question uses the same equation as the others:
q = m c (T2-T1) where
q is the heat or energy gained or lost
m is the mass of the sample
c is the specific heat in J/gC
T2 is the final temperature and
T1 is the initial temperature
Just plug in the information you are given and solve the equation for what you are trying to find.
(Note: since a change of 1 K = 1 degree C, the specific heat in J/gC or J/gK is the same thing)
