    Answer: 18634 joules

    Explanation:

    The quantity of Heat Energy (Q) released when a heated substance is cooled depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

    Thus, Q = MCΦ

    Since,

    Q = ?

    Mass of oil = 345g

    C = 0.220 J/g°C

    Φ = (Final temperature - Initial temperature)

    = 0°C - 220°C = - 220°C

    Then, Q = MCΦ

    Q = 345g x 0.220 J/g°C x - 220°C

    Q = 18634 joules (note that negative sign will not reflect in answer, because it only indicates that heat was released rather than gained)

    Thus, 18634 joules of heat is released
