    Q = 197505J

    Explanation:

    Mass (m) = 825g

    Specific heat capacity (c) = 1.8J/g°C

    Initial temperature (T1) = 22°C

    Final temperature (T2) = 155°C

    Heat energy (Q) = ?

    Q = mc∇t

    Q = mc (T2 - T1)

    Q = 825 * 1.8 * (155 - 22)

    Q = 1485 * 133

    Q = 197505J

    The heat energy required to raise it through that temperature is 197505J
