Answer

Brief Explanations:

The text states that particles in a solid are held together tightly, so "Particles in a solid are packed tightly" is true. It also says that particles in a solid are not completely still but are constantly vibrating, meaning they have thermal energy. So "Particles in a solid have thermal energy" is true. And it clearly contradicts that particles are completely still.

Answer:

Particles in a solid are packed tightly. Particles in a solid have thermal energy.
