Which of the following statements about the kinetic particle theory is not true?

• The particles of a gas move faster than those of a liquid.
• The particles of a solid have more kinetic energy than those of a gas.
• The particles that make up matter are always moving.
• The forces of attraction between the particles of a solid are very strong.

Which of the following statements about the particle of a gas is true?

• The particles of a gas vibrate about fixed positions.
• The particles of a gas are packed close together in a disorderly arrangement.
