Question

question 3. some physical properties of two samples of iodine - 127 at two different temperatures are shown in the table below. selected physical properties of iodine - 127 samples at 1 atm sample sample temperature (k) description density (g/cm³) 1 298 dark - gray crystals 4.933 2 525 dark - purple gas 0.006 these two samples are two different ____ elements. states of matter. compounds. isotopes of iodine

Explanation:

Sample 1 is in solid - dark - gray crystals form and Sample 2 is in gas - dark - purple gas form. States of matter include solid, liquid, and gas. Since they are the same element (iodine - 127) but in different physical forms based on temperature, they are different states of matter.

Answer:

B. states of matter
