My chemistry teacher is kind of weird.   He asked me when adding CuSO4 (aq) with Zn (s) calculating 10 second interval and 5 minutes cooling down. He asked me why it should be 10 second interval and 5 minutes cooling down. Even though it is mention on the worksheet what kind of answer should I give then? This is posted to all who can helped!! please if you can ANSWER THIS!! help me out, (also add the internet source if can) any means necessary!!!!

If you're not paraphrasing then I have no idea what the hell hes talking about. Measuring the temperature at 10 second intervals?
