The substance with stronger intermolecular forces is **Oxygen** because its melting point and boiling point are **higher** than Argon.
This is because Oxygen (O₂) is a polar molecule and exhibits stronger dipole-dipole interactions compared to Argon (Ar), which is a noble gas and primarily exhibits London dispersion forces. While both gases are nonpolar, the presence of stronger intermolecular interactions in Oxygen leads to higher boiling and melting points compared to Argon.
