3960 J of heat are added to a 27.6 g sample
of iron at 25

C. What is the final temperature of the iron? The specific heat of iron is
0.449 J/g · K.
Answer in units of K

  • chemistry - ,

    1)Convert 25* Celsius to Kelvin.
    Celsius + 273.15 = Kelvin

    Plug the given numbers in this formula and solve for final temperature.
    q = mcΔT

    where
    q = heat energy
    m = mass
    c = specific heat
    ΔT = change in temperature = final temperature - initial temperature
