Question

What is the relationship between thermal energy and intermolecular interaction energy of a substance in three states in terms of $X$ and $Y$?
Gas $\to$ Liquid $\to$ Solid
$\stackrel{\text{Predominance of X}}{\to }$
$\stackrel{\text{Predominance of Y}}{\to }$

• A. $X$-Thermal energy, $Y$ -Intermolecular interactions
• B. $X$-Thermal energy, $Y$-Thermal energy
• C. $X$-Intermolecular interactions, $Y$-Thermal energy
• D. $X$-Intermolecular interactions,$Y$-Intermolecular interactions

Answer 1

Answer: (C)

Intermolecular interactions increases from gas to solid. Thermal energy converts solids to liquids and liquids to gases.
