Question

A certain freezing process requires that room temperature be lowered from 40 degree C at the rate of 5 degree C every hour. What will be the room temperature 10 hours after the process begin?*​

Answer 1

Answer:

Step-by-step explanation:

Your answer is

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

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

= -10oC

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