How is the kinetic theory of matter related to gases?
The kinetic molecular theory tells us how gas molecules are supposed to behave. In doing this, it makes a few assumptions about how gases behave. Let’s have a look at them and see if they’re right:
Gas particles are infinitely small. In the real world, atoms and molecules are not infinitely small, making this incorrect.
Gas particles undergo completely elastic collisions (i.e. collisions that don’t result in the loss of energy). Perfectly elastic collisions don’t happen because some energy isn’t transferred, making this wrong.
The kinetic energy of gas particles is directly proportional to the temperature in Kelvin. As far as I know, this is correct.
