Suppose a student performed the trial 1 experiment in his classroom laboratory. After adding the magnesium, he forgot to close the lid. How do you expect his final temperature after the reaction will compare to the one you measured in this lab

The final temperature after the reaction will be lower than the one obtained in Trial 1.

Explanation:

Hello,

In this case, given the mistake of the student, we can infer that the final temperature after the reaction will be lower than the one obtained in Trial 1 since the heat from the calorimeter turns out transferred through the opening to the air surrounding it. Nevertheless, if it would have remained closed, the heat would be held into the calorimeter.

Regards.
