Question

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

• 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

The correct option is C X-Intermolecular interactions, Y-Thermal energy

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

Hence, X-Intermolecular interactions, Y-Thermal energy.
