Answer:
Given that
Let us assume that the lowered temperature as negative,
Initial temperature = 40 degree C
Change in temperature per hour = -5 degree C
Change in temperature after 10 hours = (-5) × 10 = -50 degree C
∴The final room temperature after 10 hours of freezing process = 40 degree C + (-50 degree C)
= -10 degree C
The room temperature 10 hours after the process begins= -10oC
