Answer:
Elastic collisions
Step-by-step explanation:
The collision between gas particles and the container walls are elastic collisions because there is no overall loss of kinetic energy.
This is one of the assertions of the kinetic theory of gases.
Elastic collision is a form of collision in which the two molecules does not stick together. It is random and independent in nature.
Through this assumption, we can make a wide array of assumption about the properties of gases without getting it complicated.
