What determines the state of a substance?

Number of atoms or molecules

Intermolecular forces and molecular interactions (correct)

Chemical composition

Thermal energy and motion of particles

Why do individual water molecules not exhibit wetting properties?

Because individual molecules lack H2O composition

Intermolecular forces prevent wetting at the molecular level

Due to the different physical properties in bulk compared to individual molecules (correct)

The absence of thermal energy in single molecules

In what way do ice, water, and steam differ despite having the same chemical composition?

They vary in chemical composition

Each has unique intermolecular forces

Their states of matter are distinct

They have different physical properties (correct)
