To determine the correct labels for the cells marked [tex]\( X \)[/tex] and [tex]\( Y \)[/tex] in the comparison of plasmas and solids, we need to consider what we know about the kinetic energy and density of these states of matter.
1. Kinetic Energy:
- Plasma: Plasmas have high kinetic energy. This is because the particles in a plasma are highly energized and move rapidly.
- Solid: Solids have low kinetic energy. The particles in a solid are closely packed and vibrate in fixed positions, meaning they have relatively less energy compared to plasmas.
2. Density:
- Plasma: Plasmas typically have low density. This is because the particles in a plasma are spread out over a large volume.
- Solid: Solids have high density. The particles in a solid are closely packed together, leading to a higher density.
Given this information, we can fill in the cells marked [tex]\( X \)[/tex] and [tex]\( Y \)[/tex]:
- [tex]\( X \)[/tex] should correspond to the kinetic energy of plasmas, which is high.
- [tex]\( Y \)[/tex] should correspond to the density of solids, which is high.
Thus, the correct labels for the cells are:
[tex]\[ X : \text{High}, \quad Y : \text{High} \][/tex]
Therefore, the correct answer is:
[tex]\[ X : \text{High}, \quad Y : \text{High} \][/tex]
