Question

Water cools from 68 cto 23 c in 30 min. What is the rate of temperature change?

Answer 1

1.5 c a minute. hope it helps

Answer 2

-1,5º per minute.

Step-by-step explanation:

To solve this we just need to divide the number of grades that the temperature cooled off between the amount of minutes in which that change was experienced:

Change in temperature= Final temperature-initial temperature

Ct=23-68=-45

we divide the -45º by the 30 minutes:

-45/30=-1,5

So we know that the water changed its temperature at -1,5 grades per minute.
