The particles of the substance are more orderly in region 1 than in region 3. This is because the particles are closer together and arranged in a regular pattern in region 1. This leads to more interactions between particles and slower speeds. In region 3, the particles are further apart and arranged in a more random pattern, leading to fewer interactions between particles and faster speeds.
The best comparison of the particles of the substance when it is in region 1 with the particles of the substance when it is in region 3 is that the particles are more orderly in region 1.
In region 1, the particles are close together and arranged in a regular pattern. This indicates that the particles have less freedom of motion and are more likely to interact with each other. This is consistent with the observation that the particles are slower in region 3, which is likely due to collisions between particles.
In region 3, the particles are further apart and arranged in a more random pattern. This indicates that the particles have more freedom of motion and are less likely to interact with each other. This is consistent with the observation that the particles are faster in region 1, which is likely due to fewer collisions between particles.
The question probable may be:
Which best compares the particles of the substance when it is in region 1 with the particles of the substance when it is in region 3? The particles are slower in region 3. The particles are more orderly in region 1. The particles have more kinetic energy in region 1. The particles have less freedom of motion in region 3.
