    Let us take the lowered temperature as negative.
    Initial temperature = 40 degree Celsius
    Change in temperature = -5 degree Celsius
    Change in temperature after 10 hours = (-5)*10=-50 degree Celsius
    Therefore, the final room temperature after 10 hours of freezing process = 40+(-50) = -10 degree Celsius.
