Question 11

Q11)A crystal of iodine is placed in a closed flat bottom flask and heated. State how you would conclude from the observations seen, that inter particles space is minimum in solids and maximum in gases.

Solution :

A crystal of iodine is heated in a closed flask and occupies only the space at the bottom of the flask. After heating, the crystal of iodine converts into vapour and fills the whole flask with iodine vapours.

This shows that particles of solid are closely packed and occupy less space while particles of gases are loosely packed and occupy the complete space available.
