• potential energy of the molecules

• density of the material

• kinetic energy of the molecules

• size of the molecules

Which pair of properties apply to a substance in the solid state but not the liquid state?

Chihiro was boiling water to make pasta. As the water started boiling, bubbles formed on the surface and steam rose. What caused the appearance of the water to change?

• The heat caused some of the water molecules to move apart from each other, becoming less dense and floating on the surface.

• The heat caused some of the water molecules to move apart from each other, becoming less dense and rising from the pot.

• The heat caused some of the water molecules to move closer together, becoming more dense and floating on the surface.

• The heat caused some of the water molecules to move closer together, becoming more dense and rising from the pot.
