It takes 51.0 j to raise the temperature of an 8.60 g piece of unknown metal from 13.0 C to 25.0 C. What is the specific heat for the metal?

  • college -

    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))
    51 = 8.6*c*(25-13)
    c = 0.494 J/g*K
    (always check significant figures)

    so there,, :)
