Answer:

Hope This Will Help You

Step-by-step explanation:

Given that

Let us assume that the lowered temperature as negative,

Initial temperature = 40 degree C elsius

Change in temperature per hour = -5 degree Celsius

Change in temperature after 10 hours = (-5) × 10 = -50 degree C elsius

∴The final room temperature after 10 hours of freezing process = 40 degree Celsius + (-50oC)

= -10oC

The room temperature 10 hours after the process begins= -10oC
