Question

A cooling machine requires that room temperature to be lowered from 50°C at the rate of 5°C every hour. What will be the room temperature 8 hours after the process begins??​

Answer 1

Answer:

SOLUTION

Step-by-step explanation:

The room temperature after 8 hours process begins is 10°C. Hence, the room temperature after 8 hours process begins is 10°C.

Answer 2

Answer: The room temperature after 8 hours process begins is 10°C.

Step-by-step explanation:

Since we have given that

Room temperature = 50° C

At every hour, it reduces at the rate of = 5° C

So, After 8 hours, it reduces by

\begin{lgathered}8\times -5^\circ C\\\\=-40^\circ C\end{lgathered}

8×−5

C

=−40

∘

C

So, Room temperature after 8 hours , it becomes,

\begin{lgathered}50^\circ C-40^\circ C\\\\=10^\circ C\end{lgathered}

50

∘

C−40

∘

C

=10

C

Hence, the room temperature after 8 hours process begins is 10°C.
