How Do You Solve a Delta T Analysis Problem in Homework?
Click For Summary
Discussion Overview
The discussion revolves around solving a delta T analysis problem in a homework context, focusing on the definitions of initial and final temperatures in a thermal system.
Discussion Character
- Homework-related
Main Points Raised
- One participant expresses confusion about how to approach the problem.
- Another participant inquires about the initial and final temperatures relevant to the analysis.
- A participant clarifies that the final temperature should be the maximum temperature observed after a reaction, not the temperature after the system has cooled down.
- There is mention of the potential need to extrapolate to determine the maximum temperature if the system cools before fully heating up, although this may not apply in the current case.
- A later reply confirms the clarity of the explanation provided, indicating it aligns with information found elsewhere.
Areas of Agreement / Disagreement
Participants appear to agree on the definition of final temperature as the maximum observed after the reaction, but there is no consensus on how to proceed with the delta T analysis problem itself.
Contextual Notes
There are unresolved aspects regarding the specific steps needed to solve the delta T analysis problem and the implications of temperature measurements during the reaction.

What was the initial temperature? What was the final temperature?

The initial temperature is 24 degrees Celsius and the final temperature is 29 degrees Celsius. However, 5 degrees Celsius as a delta T is not an option given :/

Ah, I see where your problems steams from.
Final temperature is not the one measured after the system had time to cool down (actually if you wait long enough final temperature will be the same as the starting one). Final temperature is the one observed after the reaction ended (so it is the maximum temperature observed).
Sometimes things are slightly more complicated, as the systems cools down even before it completely heats up, then, to get the maximum temperature, you may have to extrapolate. But it doesn't look like it is the case here.

Yes, this is exactly the explanation I found elsewhere! Thank you so much, Borek!
