Answer:
because there is more energy in the gas molecules and gas molecules are loosely packed
they have less intermolecular force of attraction

Answer:
When chemical substances such as perfume are let loose in a room, their particles mix with the particles of air. The particles of smelly gas are free to move quickly in all directions. They eventually spread through the whole room from an area of high concentration to an area of low concentration.
