Question

During Mr. Nye's science class, students were expected to identify various substances using physical properties they could easily measure. Mr. Nye gave each of the five groups a green, metal cube. The students had to identify what metal the cube was made of. The length of each side was 3.0 cm and the mass was 270 grams.
What property should Mr. Nye's science students use to identify the metal in the cubes?

A) color

B) density

C) mass

D) volume

Answer 1

Hey there

The students should use density. 

Answer 2

Density is the best property to use, as while multiple different metals could create cubes with the same color, mass, or volume, no different metal could create a cube with the same mass and volume.  Density is based on mass and volume, and as a result no two different metals will have the same density.
