Question

a certain freezing process require that room temparature be lowerd from 32°C at the rate of 5°C every hour .What will be the room temperature 8 hour after the freezing process begins​

Answer 1

Step-by-step explanation:

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

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

= -10oC

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

Answer 2

Answer:

-8 degrees Celsius

Step-by-step explanation:

Step 1: Find the temperature after 8 hours or (5)(8)=40

Step 2: add 32 to -40 or -40+32= -8
