Why was it important to allow all the investigation materials to assume room temperature before beginning the experiment?
hram777 [196]

Answer:

The temperature is kept at room temperature and mostly preferred to be constant, so that the temperature does't be a variable factor effecting the accuracy of experiment.

Temperature is kept constant to take it as a control factor, so that experimental results are not effected by such outside factors. Such control variables are important in experiments as they minimize the influences from outside.
