Solution
- In gases, the intermolecular force of attraction between the particles is least as compared to solid and liquid.
- Due to the negligible intermolecular force of attraction, gaseous particles have the highest energy, that's why they are in random motion.
- So whenever gases are provided with available space, they move around and fill the complete space.
- Thus, the gas tends to fill the container in which it is kept.
