Question

Gases have low density than that of solids and liquids because of __________

(a) no thermal energy

(b) higher intermolecular energy

(c) both intermolecular energy and thermal energy are the same

(d) higher thermal energy

The question was asked in an online interview.

I would like to ask this question from States of Matter in chapter States of Matter of Chemistry – Class 11

Answer 1

The correct answer is (d) higher thermal energy

The best I can explain: In gases, there is less amount of intermolecular energy and higher amount of thermal energy. As we know that thermal energy separates some molecules from one another so gases have low density than that of solids and liquids.
