For the most part, you can ignore the forces of attraction among the particals in which of the following?

The force of attraction for the states of matter, which can be ignored for most part of calculation or observation, is the gases.

Explanation:

Gases have incredibly less force of attraction. The inter molecular space between the gaseous molecules are so vast that the force of attraction between them is negligible.

And, for a matter of assumption for smooth calculation, factors which are negligibly less can be ignored. And, thus, for most part of science, the attractive force is ignored among the gaseous particles.
