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

Answer 1

The statement "Particles in a solid are completely still" is not accurate. While it is true that particles in a solid are packed tightly together, they are not completely still. Instead, they vibrate around fixed positions due to thermal energy. The vibrations increase with temperature, meaning that as the thermal energy of the solid increases, the amplitude of the vibrations of the particles also increases. This characteristic is fundamental to the behavior of solids and contributes to their properties such as rigidity and thermal conductivity.
