Question

particles in each state of matter behave differently because they have different amounts of thermal energy. in a solid, the particles are held together tightly, and they do not move around freely. because the particles stay in about the same place, a solid generally keeps a certain shape. even though particles in a solid cannot move past one another, they are not completely still. the particles are constantly vibrating, or moving back and forth, in place. select all the true statements. particles in a solid do not have thermal energy. particles in a solid are packed tightly. particles in a solid do not move.

Explanation:

The text states that particles in a solid are held together tightly. It also mentions that particles in a solid are constantly vibrating in place, so they are not completely still, and all matter has some thermal energy.

Answer:

Particles in a solid are packed tightly.
