1)Particles in a gas move faster as the temperature increases.
2)Particles in a liquid are packed closely together,but are not confined to specific positions.
3)Particles in a gas vibrate back and forth about an average position.
A) 1 only
B) 2 only

1) This is true according to the kinetic-molecular theory, stating that as the temperature of a gas increases, so does the average kinetic energy of the particles, leading to faster movement.
2) This is also true according to the kinetic-molecular theory, stating that particles in a liquid are close together but not arranged in a specific pattern.
3) This statement is incorrect according to the kinetic-molecular theory, as it describes the behavior of particles in a solid, not a gas. Particles in a gas move freely and rapidly in all directions.
