Answer 2

Answer:

Here's your answer

Step-by-step explanation:

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= -10 degree C
