ATI TEAS 7 Science Practice Test Question 2

In the context of the ATI TEAS 7 Science Practice Test, understanding the behavior of particles during state changes is critical. Question 2 raises the inquiry about which state change causes particles to become more disordered, listing options such as deposition, freezing, and condensation. To clarify, during phase transitions, the degree of particle disorder—also known as entropy—varies. Deposition is the process where gas turns directly into solid, which leads to increased order as particles go from highly disordered gas to a structured solid state. Similarly, freezing (liquid to solid) and condensation (gas to liquid) involve particles moving from less ordered to more ordered phases, decreasing disorder in the system. Therefore, the state changes that cause particles to become more disordered involve transitions from solid to liquid or liquid to gas phases—melting or vaporization—not listed among the options. Understanding these principles helps students to better grasp thermodynamics concepts, which are frequently tested on the TEAS exam. By focusing study efforts on how entropy changes during state changes, students can gain an improved conceptual foundation, which is essential for scoring well in the science section. Engaging with practice questions like this supports active learning and prepares students for similar questions on test day.
