1. 1.

   A chemistry student analyzes two pure aluminum cylinders, Sample X (mass = 15.0 g, volume = 5.56 cm³) and Sample Y (mass = 60.0 g, volume = 22.24 cm³), both stored at room temperature. The student aims to determine which measured attributes can be used to establish the identity of the metal without being affected by sample size. Which statement correctly identifies and classifies the properties of these two samples?

   • A) Density and temperature are intensive properties that are identical for both samples, whereas mass and volume are extensive properties that vary with sample size.
   • B) Mass and volume are intensive properties that remain constant per unit sample, whereas density is an extensive property that quadruples for Sample Y.
   • C) Density and mass are extensive properties because they both directly increase when more matter is gathered into a single object.
   • D) Temperature and volume are intensive properties because they can be measured directly with standard laboratory equipment without destroying the sample.
