    Given that
    Let us assume that the lowered temperature as negative,
    Initial temperature = 40oC
    Change in temperature per hour = -5oC
    Change in temperature after 10 hours = (-5) × 10 = -50oC
    {tex}\therefore{/tex} The final room temperature after 10 hours of freezing process = 40oC + (-50oC)
    = -10oC
    The room temperature 10 hours after the process begins= -10oC
