Which of the following statements related to kinetic-molecular theory of gases is correct for an ideal gas?

   

There are no attractive or repulsive forces between and among gas particles.

   

Gas particles move slowly in a chaotic pattern until they collide with something.

   

For a given amount of gas, the smaller the volume of the container, the fewer the collisions that occur with the container walls, since there is less surface area.

   

The density of a gas is somewhat lower than that of a liquid.

   

The more gas particles there are in a container, the more frequently they collide with one another, so the particles stick together, resulting in a lower pressure.

Expert Answer

Step 1

The Kinetic molecular theory of gases is a model that explains experimental observation about the gases under the normal temperature and pressure conditions encounter in the environment

 

Given:

  • There are no attractive or repulsive forces between and among gas particles.
  • Gas particles move slowly in a chaotic pattern until they collide with something.
  • For a given amount of gas, the smaller the volume of the container, the fewer the collisions that occur with the container walls, since there is less surface area.
  • The density of a gas is somewhat lower than that of a liquid.
  • The more gas particles there are in a container, the more frequently they collide with one another, so the particles stick together, resulting in a lower pressure.
Step 2

Kinetic-molecular theory of gases for an ideal gas is:

  • Gases are composed of small and widely separated particles
  • Particles of a gas behave independently of one another
  • Each particle in a gas is in rapid, straight-line motion, until it collides with

another molecule or with its con...
