Kelsha makes a table to compare plasmas and solids.
| & Plasma & Solid |
| Kinetic energy | X |
| Density | | Y |
Which labels belong in the cells marked [tex]$X$[/tex] and [tex]$Y$[/tex]?
A. X: High, Y: High
B. X: High, Y: Low
C. X: Low, Y: High
D. X: Low, Y: Low
Answer (2)
Plasmas have high kinetic energy.
Solids have high density.
Therefore, X (kinetic energy of plasma) is High, and Y (density of solids) is High.
The correct labels are X: High, Y: High. X : H i g h , Y : H i g h
Explanation
Understanding the Properties Let's analyze the properties of plasmas and solids to determine the correct labels for kinetic energy (X) and density (Y).
Kinetic Energy of Plasma Plasmas are superheated gases where electrons are stripped from atoms, resulting in a collection of free-flowing ions and electrons. Due to this high energy state, plasmas have high kinetic energy. Therefore, label X should be 'High'.
Density of Solids Solids, on the other hand, have tightly packed atoms or molecules held together by strong forces. This close arrangement results in a high density. Therefore, label Y should be 'High'.
Determining the Labels Based on our analysis, the correct labels are: X: High Y: High
Examples
Understanding the properties of matter, such as kinetic energy and density, is crucial in various fields. For example, in material science, knowing the density of a solid helps engineers choose the right materials for construction. Similarly, understanding the kinetic energy of plasma is essential in designing fusion reactors, where plasma is used to generate energy. This knowledge also helps in developing plasma TVs and other plasma-based technologies.
The kinetic energy of plasma is high, and the density of solids is also high. Therefore, the correct labels for the table are X: High and Y: High. The chosen option is A: X: High, Y: High.
