As we stand and watch the hot air balloon rise in the sky, we can imagine what is happening at the microscopic level to the gas molecules inside the balloon. As the balloon rises, the gas molecules are

• moving faster and spreading apart.

• slowing down and moving closer together.

• gradually escaping from the confines of the balloon.

• all collecting at the top of the balloon, pushing upward.

As ice transforms into steam,

• new molecules are formed.

• the types of atoms are changed.

• energy is absorbed by the molecules.

• the mass of the molecules is increased.

Solids are often defined as having a definite shape, while gases and liquids have no definite shape. This can best be explained by the fact that

• solids have a more ordered arrangement of atoms than liquids and gases.

• in solids molecules move faster than in liquids or gases.

• solids have less internal energy than liquids and gases.

• solids have the least orderly internal structure.
