Q = mc(T2-T1)
where Q = heat in J, m = mass in kg, c = specific heat capacity in J/(g*K), T = temperature in Kelvin,,
**change in temperature can have unit degree Celsius or Kelvin,, thus you can use it interchangeably (what i mean is that the units for c can also be J/(g*C))
therefore:
51 = 8.6*c*(25-13)
c = 0.494 J/g*K
(always check significant figures)
so there,, :)
