Question

3.
A certain freezing process requires that the room temperature be lowered from 40°C at
the rate of 5°C every hour. What will be the room temperature 10 hours after the process
begins?​

Answer 1

Answer:

10 - degree c

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 + (-50oC)

= -10 degree C

The room temperature 10 hours after the process begins= -1 degree C
