Helium, as it's gas at room temperature.
Iron expands the least when the temperature is lowered, followed by wood and then water. Helium does not expand or contract significantly with changes in temperature due to its unique properties as a gas.
Argon is better. Helium can't compare to it, not in terms of cost, usefullness, availability, personality, attractive appearance, intelligence, or ambition.
8 electrons in its outmost shell (only helium has two)
Helium is less dense than oxygen and nitrogen. It is about 7-8 times less dense than air, which is a mixture of nitrogen and oxygen.

fossil fuels
Helium gas. But the box should be air tight. Or else you can create a vacuum in it. Holes. Obviously it would make the box lighter, but the box is not actually holding anything, just air.
You can compare brown eyes to an oak tree, wood, a animal . And hair idk

Just to compare them and not to weigh them, then you could use a seesaw.
