Which is true about the movement of gas particles? particles travel in straight-line paths until they collide with other objects. the term "random walk" refers to the speed of particles. particles will partially fill their container. the motion of one particle depends on the motion of all the others. description?

the first option: travel in straight-line paths until they collide with other objects.


Justification:


The kinetic molecular theory of gases deal with the movement of gas particles (molecules) to explain the behavior of the gases.


These are the main assumptions made by the model:


1) Size of the particles: The gases are formed by tiny particles whose volume is negligible in comparisson to the volume of the vessel that contain the gases.


2) Intermolecular forces: There are not either attraction or repulsion forces between the molecules.

3) Motion: the particles are in constant random motion. They move in straight line until they collide with each other or the walls of the vessel. The partilces do not lose energy when the collide with each other.

Those assumptions let to explain the low density of the gases, the compression and expansion, among other properties of the gases.

What are the choices?
