Question

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. ⤵️⤵️

So, in 10 hours the temperature would be decreased by 10*5 = 50°C.

Answer 2

Answer:

heya!!ur answer is this ⤵️

Step-by-step explanation:

Given that

Let us assume that the lowered temperature as negative,

Initial temperature = 40⁰C

Change in temperature per hour = -5⁰C

Change in temperature after 10 hours = (-5) × 10 = -50⁰C

∴The final room temperature after 10 hours of freezing process = 40⁰C + (-50⁰C)

= -10⁰C

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