Answer:
-40.0 °C
Explanation:
Change in temperature can be written as [tex]\displaystyle{\Delta T = T_2-T_1}[/tex]. The variables are defined below here:
[tex]\displaystyle{\Delta T}[/tex] means change in temperature.
[tex]\displaystyle{T_2}[/tex] means the final temperature value.
[tex]\displaystyle{T_1}[/tex] 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:
[tex]\displaystyle{\Delta T=25.0-65.0}\\\\\displaystyle{\Delta T = -40.0}[/tex]
Therefore, the change in temperature is -40.0 °C.
