Question 16

When purple iodine vapor ( $I2(g)\text{I}_2\text{(g)}$ ) comes into contact with a cold surface, it deposits directly to form shiny, dark-grey solid iodine crystals ( $I2(s)\text{I}_2\text{(s)}$ ).

Explain why this deposition process is classified as a physical change rather than a chemical change.
