**jai**, Wednesday, October 27, 2010 at 3:29amQ = 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,, :)
