    To solve for the heat needed, use the equation:

    Q = m x c x ΔT

    Where:

    Q is the heat needed

    m is the mass of (block of) aluminum

    c is the specific heat capacity of aluminum

    ΔT is the change in temperature

    Solution:

    Q = m x c x ΔT

    Q = (5g) x (0.902 J/g•°C) x (37.0°C - 22.0°C)

    Q = (5g) x (0.902 J/g•°C) x (15°C)

    Q = 67.65 J
