Answer:
B. Maria wrapped the ice cube tightly in cotton and aluminum foil.
Explanation:
According to this question, a class is performing an experiment to keep an ice cube solid for as long as possible. However, in the experimental procedure that will be used to actualize this aim, certain protocols must be duly observed to avoid error in the experiment.
Among the listed options containing actions taken by students, wrapping the ice cube tightly in cotton and aluminum foil is a likely source of error to the experiment. This is because aluminum, owing to its metallic properties, is a good conductor of heat. Hence, Aluminum foil will conduct heat and cause the ice cube to melt faster than normal.
This will jeopardize the aim of the experiment, which is to keep an ice cube solid for as long as possible.
