Keisha makes a table to compare plasmas and solids.

\begin{tabular}{|l|c|c|}
\hline & Plasma & Solid \\
\hline Kinetic energy & [tex]$X$[/tex] & \\
\hline Density & & [tex]$Y$[/tex] \\
\hline \hline
\end{tabular}

Which labels belong in the cells marked X and Y?

A. [tex]$X:$[/tex] High, [tex]$Y:$[/tex] High
B. [tex]$X:$[/tex] High, [tex]$Y:$[/tex] Low
C. [tex]$X:$[/tex] Low, [tex]$Y:$[/tex] High
D. [tex]$X:$[/tex] Low, [tex]$Y:$[/tex] Low



Answer :

To determine which labels belong in the cells marked X and Y, we need to compare the properties of plasmas and solids with respect to kinetic energy and density.

Firstly, let's examine the kinetic energy:
- Plasma is a state of matter where the particles are highly energetic. This high energy results in the particles moving rapidly and colliding frequently. Therefore, the kinetic energy in plasma is high.
- Solid, on the other hand, has particles that are closely packed together in a fixed position and only vibrate in place. This implies that solids have low kinetic energy.

Considering these points, the label for kinetic energy in plasma (marked as X) is "High".

Next, let's evaluate the density:
- Solid typically has particles that are very closely packed together, which makes solids have a high density.
- Plasma usually consists of ionized gas with freely moving charged particles, resulting in a much lower density compared to solids.

Therefore, the label for density in solids (marked as Y) is "High".

Putting it all together:

[tex]\[ \begin{tabular}{|l|c|c|} \hline & Plasma & Solid \\ \hline Kinetic energy & High & \\ \hline Density & & High \\ \hline \end{tabular} \][/tex]

Hence, the correct labels for the cells marked X and Y are:
- [tex]\(X: \text{High}\)[/tex]
- [tex]\(Y: \text{High}\)[/tex]
