Why can a liquid change to take the shape of its container but NOT expand to fill the container itself?

• because the particles of a liquid have a definite shape but no definite volume

• because the particles of a liquid are held together loosely enough to flow, but not so loose that they expand

Why do the air molecules inside a balloon speed up as the temperature gets warmer?

• because the heat is transferred to the molecules and gives them more kinetic energy

• 
  because the warmer air allows the particles to be free from gravitational forces

• because the heat liberates the potential energy inside each molecule
