Explanation:-
- Each molecule or atom in a gaseous sample behaves independently of the others. Therefore, they are equally likely to travel in any direction at any given time, making their motion random.
- Gas particles are in constant motion and share a large number of rapid, elastic collisions. These collisions are perfectly efficient, meaning they don't lose kinetic energy.
- Kinetic theory of gases assumes randomness: According to the kinetic theory of gases, the motion of gas particles is random, with their direction and speed constantly changing due to collisions with other particles and the container walls.
- The intermolecular space in gases is much larger than in solids or liquids. This property gives gas molecules freedom to move randomly without a fixed path.
- The speed at which gas particles move is influenced by temperature and pressure. Higher temperature means more kinetic energy and faster, more random motion. Inversely, higher pressure can hinder their movement, but not the random nature of it.
- No significant intermolecular forces: Unlike in liquids and solids, intermolecular attractive forces in gases are negligible because particles are far apart from each other. Therefore, they are free to move in a random manner.
Conclusion:-
So, The motion between the particles in a gaseous substance is Random
