Based on the property of gases, 1-gram sample of hydrogen gas, H₂ in a sealed 1-liter container will occupy the container completely and uniformly.
What is the nature of a gas?
Gases are one of the states of matter.
Gas molecules have negligible forces of attraction between them, therefore, they are always in motion.
Gases do not have a specific shape or volume, rather they fill up every available space in their container.
Of the given option, only H₂ is a gas.
Therefore, 1-gram sample of hydrogen gas, H₂ in a sealed 1-liter container will occupy the container completely and uniformly.
