Sunidhi made a study chart about changes in states of matter:

\begin{tabular}{|l|c|}
\hline \multicolumn{1}{|c|}{X} & Y \\
\hline melting & freezing \\
\hline sublimation & deposition \\
\hline
\end{tabular}

Which headings best complete the chart?

A. X: Solid Directly to Liquid, Y: Liquid Directly to Solid

B. X: Liquid Directly to Solid, Y: Solid Directly to Liquid

C. X: Heat Is Released, Y: Heat Is Absorbed

D. X: Heat Is Absorbed, Y: Heat Is Released

To determine the appropriate headings for Sunidhi's study chart, let's first review the processes involved in each column:

### Column X:
1. Melting: The process where a solid changes to a liquid. This involves absorbing heat.
2. Sublimation: The process where a solid changes directly to a gas. This also involves absorbing heat.

### Column Y:
1. Freezing: The process where a liquid changes to a solid. This involves releasing heat.
2. Deposition: The process where a gas changes directly to a solid. This also involves releasing heat.

Given this understanding of the phase changes and the heat transfer involved:

- Melting and Sublimation are processes where heat is absorbed.
- Freezing and Deposition are processes where heat is released.

Therefore, the headings that best complete the chart are:
- [tex]$X$[/tex]: Heat Is Absorbed
- [tex]$Y$[/tex]: Heat Is Released

Thus, the correct answer is:
[tex]$X$[/tex]: Heat Is Absorbed, [tex]$Y$[/tex]: Heat Is Released.
