Final answer:
The kinetic molecular theory of gas behavior makes several assumptions, including that gas molecules are in constant motion, collide elastically with each other and container walls, and have no forces of attraction or repulsion between them.
Step-by-step explanation:
The kinetic molecular theory of gas behavior assumes the following:
- Gases consist of very large numbers of tiny spherical particles that are far apart from one another compared to their size.
- Gas particles are in constant rapid motion in random directions.
- Collisions between gas particles and between particles and the container walls are elastic collisions.
- There are no forces of attraction or repulsion between gas particles.
- The average kinetic energy of gas particles is dependent upon the temperature of the gas.
For example, the assumption that gas particles are in constant motion explains why gases tend to fill the container they are placed in. Additionally, the assumption that there are no forces of attraction or repulsion between gas particles explains why gases can easily be compressed or expanded.
