Answer: repeating the experiment three times for each temperature
using three different temperatures instead of only two
using three different surface areas instead of only two
An experimental error is an error than occurs due to lack of precision or accuracy. The experimental error can decrease by following procedures like
1. Repeating the experiment three times for each temperature: A temperature is an variable factor therefore, to derive correct result, an experiment should be performed at least thrice to deduce consistency in data at every trial and this consistent data should be utilize to conclude the final result. Hence, chances of errors will decrease.
2.Using three different temperatures instead of only two: The observations obtained after three different temperatures should be included, if there is a change in the observation then it will depict errors in the experiment.
3. Using three different surface areas instead of only two: Surface area can either enhance or reduce the rate of activity in a experimental set. Therefore, to obtain consistent results the experimental activity is checked upon different surfaces.
