Question

Each of four groups of students determined and recorded the melting point of a solid compound. if the actual melting point is 113°c, which group had the best precision?

Answer 1

the answer to your question is

Delocalized electrons move freely from atom to atom forming what is known as a sea of electrons. This sea of electrons can absorb part of the impacts avoiding that the structure of the atoms be broken, so the mass of metal is re-shaped in contrast of what happen with the cristal structure of salts, for example.

Answer 2

Group 4

Step-by-step explanation:

Precision means the closeness of repeated measurement.

Accuracy means the closeness of measurement to its true value.

Measurement can be precise but not accurate.

Group 4 measurement has the lowest range which is 110 - 111, hence, they are the most precise in their measurement.
