Question

What is the change in

temperature when water goes
from 65.0 °C to 25.0 °C?
AT = [?] °C

Answer 1

-40.0 °C

Step-by-step explanation:

Change in temperature can be written as
`\displaystyle{\Delta T = T_2-T_1}`. The variables are defined below here:

`\displaystyle{\Delta T}` means change in temperature.

`\displaystyle{T_2}` means the final temperature value.

`\displaystyle{T_1}` means the initial temperature value.

From the question, we know the temperature changes from 65.0 °C to 25.0 °C. Therefore, our initial temperature is 65.0 °C and final temperature is 25.0 °C.

Hence:

`\displaystyle{\Delta T=25.0-65.0}\\\\\displaystyle{\Delta T = -40.0}`

Therefore, the change in temperature is -40.0 °C.
