FREE Expert Solution

We are asked which of the following are assumptions with the kinetic theory of an ideal gas?

A gas is seen as a collection of molecules or individual atoms that are in constant motion. 

The Kinetic-Molecular Theory tries to use data of real gases to predict how an ideal gas would behave if they existed.

Ideal gases are imaginary and don’t actually exist. However, if they did exist then there would be certain characteristics that gas would need to possess in order to be an ideal gas.
