The force of attraction for the states of matter, which can be ignored for most part of calculation or observation, is the gases.
<u>Explanation:
</u>
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.
Answer:
Explanation:
A combination of two controlled variables will make an experiment the most reliable.
Variables are the values that we take under any circumstance while doing an experiment so that we can keep on changing and get new results at the end.
It is important to have them in pair so that two values can be kept on changing in terms of any constant condition. This will help to get better results in over all experiment data.
