How should the model be changed to show the particles of a solid?

• Increase the velocities of the particles, and increase the space between the particles.

• Increase the velocities of the particles, and decrease the space between the particles.

• Decrease the velocities of the particles, and increase the space between the particles.

• Decrease the velocities of the particles, and decrease the space between the particles.

Answer explanation

The correct answer for Part A is choice (D) Decrease

the velocities of the particles, and decrease the space

between the particles. Choice (A) is incorrect because it

would increase the temperature and not produce a solid.

Choice (B) is incorrect because it would increase the

temperature and density but would not produce a solid.

Choice (C) is incorrect because the space between the particles would decrease.
