Homework Help: What formula do I use?

  1. Dec 11, 2011 #1
    The question is "A 21 kg aluminum block absorbs 1.5 x 10^5 J of energy. Calculate the change in temperature."
    1. The problem statement, all variables and given/known data
    m = 21 kg

    2. Relevant equations
    Q=m x c x T ?

    3. The attempt at a solution

    You use the formula you listed under "Relevant equations"

    It is often listed as Q=m x c x ΔT to emphasise the change in temperature. You will also need to look up the specific heat capacity of Aluminium [the c].

    NOTE: metal names end in "ium" Calcium, Sodium, Ferrium [Iron] etc. That is why it is actually Aluminium :rolleyes:
