Particle model of solids, liquids and gases Transitional Reasoning Practice

Questions

1. 1.

   A student investigates three samples (1, 2, and 3) of the same pure substance held in separate closed containers. Sample 1 maintains a fixed volume but adapts to the shape of the bottom of its container, Sample 2 expands to completely fill both the shape and volume of any container, and Sample 3 maintains a rigid shape and fixed volume. Based on the particle model of matter, which statement correctly compares the arrangement and motion of particles in these samples?

   • A) Particles in Sample 2 have negligible attractive forces and move rapidly in all directions, whereas particles in Sample 3 vibrate about fixed positions in a regular lattice.
   • B) Particles in Sample 1 are locked in a rigid arrangement with no translational motion, whereas particles in Sample 2 slide past one another while remaining closely packed.
   • C) Particles in Sample 3 have the greatest average spacing between them, allowing this sample to be compressed much more easily than Sample 1.
   • D) Particles in Sample 1 move completely independently of each other at high speeds, whereas particles in Sample 2 are held together by strong forces in fixed positions.
