Final answer:
Hydrogen would condense with the least amount of pressure because it has the weakest intermolecular forces and the lowest molecular mass. Nitrogen and Oxygen would require more pressure due to their heavier molecular masses and stronger intermolecular forces, with Oxygen needing the most pressure.
Step-by-step explanation:
The question at hand is which gas would condense with the least amount of pressure among Hydrogen (H2), Nitrogen (N2), and Oxygen (O2). To address this, we must look into the physical properties of gases, particularly the intermolecular forces and the molecular mass.
Hydrogen, being the lightest and having the weakest intermolecular forces due to its small size and lack of polarity, would condense with the least amount of pressure. Nitrogen and Oxygen, while both diatomic molecules like Hydrogen, are heavier and have stronger intermolecular forces compared to Hydrogen.
Hence, they would require more pressure to condense. Oxygen, due to having a slightly higher molecular mass and stronger intermolecular bonds than Nitrogen, would require a bit more pressure than Nitrogen to condense. Therefore, all gases would not condense with the same amount of pressure; Hydrogen would require the least, followed by Nitrogen, and then Oxygen requiring the most.
