Deriving Specific Heat Equations

  1. Feb 9, 2009 #1
    1. The problem statement, all variables and given/known data

    Derive the Following Equations:
    c = [(m_w*c_w + m_c*c_al) (T_e - T_i)] / m_s*(T_s - T_e)
    and
    L = (m_w*c_w + m_c*c_al) * (T_i - T_e) - m_I*c_w * [(T_e- T_m)/m_I]

    2. Relevant equations

    T_i - initial temp of water and calorimeter
    T_m - melting temp of ice
    T_e - equilibrium temp of system
    m_w- mass of water
    m_c - mass of calorimeter
    m_I - mass of ice
    c_w - specific heat of water
    c_al - specifical heat of aluminum
    L - unknown heat of fusion


    3. The attempt at a solution

    ...trying to receive help from my teacher's assistant, but not being able to do so :[

    Any attempts at either equations, wrong or right, will be fully appreciated.:smile:
