Question

water vapor, liquid water, and ice all have the same chemical composition but differ in the arrangement and activity of their

select one:
○ a. bonds.
○ b. molecules.
○ c. enzymes.
○ d. ions.

Explanation:

Water vapor, liquid water, and ice are different states of water (H₂O). In different states, the molecules' arrangement (e.g., in ice, molecules are more ordered; in vapor, more spread out) and activity (kinetic energy, movement) differ. Option a: Bonds in water (covalent O - H bonds) don't change between states. Option c: Enzymes are biological catalysts, not related to water states. Option d: Ions aren't the focus here as water in these states is mostly H₂O molecules, not ions. So the correct factor is molecules.

Answer:

b. molecules.
