Intermolecular forces between molecules of ideal gas are:
Correct answer: D. Absent
- A. Strong
- B. Moderate
- C. Weak
- D. Absent
Explanation
In an ideal gas, it is assumed that the intermolecular forces between gas molecules are absent. This is a key assumption in the ideal gas law (PV = nRT).

About Real and Ideal Gases
An ideal gas is modelled as particles with negligible volume and no intermolecular attraction, obeying Boyle's, Charles's and Avogadro's laws through PV = nRT. Real gases deviate from this behaviour, especially at high pressure and low temperature, because particle volume and attractive forces matter; the van der Waals equation explains these corrections.
