How often should the temperature of the mixture be measured during the experiment?

Measuring the temperature of the mixture every 30 seconds provides a balance between obtaining sufficient data points to analyze the temperature changes during the experiment while not being overly frequent, which could lead to unnecessary complications or delays in the experiment's progress. This interval allows for a thorough observation of the temperature trends, helping to identify any rapid changes or patterns that may occur in the mixture.

In contrast, measuring every minute may result in missing quick fluctuations in temperature that could be significant to the experiment's outcome. On the other side, measuring every 10 seconds might create an excessive amount of data to sort through and could also interrupt the experiment, making it less efficient. Therefore, a 30-second interval strikes a good compromise, ensuring comprehensive data collection without overwhelming the research process.
