    The heat energy required to raise the temperature is 297 joules.

    The energy required is calculated by the formula

    Q=mCΔT

    here, m is the mass, C is the specific heat, ΔT is the temperature difference

    Plugging the given values in the above equation

    Q=10*0.90 * (55-22)

    =297 joules

    The heat energy required to raise the temperature is 297 joules.
