Question 4
It is important to label the ring stands, cooling plate, and egg carton with labels 1-3 because:
the crucibles will cool at different rates. Crucibles that cool faster will have different masses that crucibles that take longer to cool. This may affect the mass
calculations in the experiment.
O it is good practice to conduct an organized experiment in the laboratory.
O each crucible will look different in appearance. Labeling the crucibles will make it easier to monitor during the experiment.
the empty crucibles have different masses and mixing up the crucibles will affect the mass calculations in the experiment.
