Below are sample questions representative of the exercises included on this worksheet and related 9.16 States of Matter and Particle Motion skill assessments:

Problem 1Difficulty: Mastery

Which explanation is most consistent with an NGSS-style particle model of states of matter?

AParticles change into different elements every time a state change occurs.

BMacroscopic state depends only on color, because color controls particle motion.

CMacroscopic state depends on particle spacing, motion, energy, and interactions, not only on the substance name.

DA substance has one permanent state no matter what energy changes occur.

Solution & Explanation:A strong model links observable properties to particle spacing, motion, energy, and attractions. The same substance can exist in different states under different conditions.

Problem 2Difficulty: Mastery

Use the energy-scale particle diagram. Which progression best matches increasing particle energy and freedom of motion?

ASolid to liquid to gas to plasma

BPlasma to gas to liquid to solid

CLiquid to solid to plasma to gas

DGas to solid to liquid to plasma

Solution & Explanation:The diagram's energy arrow runs from close ordered particles to close disordered particles, then widely spaced neutral particles, then charged particles.

Problem 3Difficulty: Mastery

A plasma cools and electrons recombine with ions to form mostly neutral gas particles. Which statement best describes this change?

ACharged particles become neutral particles, and energy is released from the plasma.

BParticles become fixed in a crystalline solid instantly.

CNeutral gas particles become charged particles, and energy is absorbed by ionization.

DAll particles disappear because plasma is not matter.

Solution & Explanation:Recombination is the reverse of ionization. Electrons join ions, forming neutral particles and releasing energy.
