Which property(ies) listed below is(are) consistent with the gaseous state of matter ?
I. Gases have a lower density than liquids or solids and their densities change to a large extent as the temperature changes.
II. Gases are easily compressed to smaller volumes.
III. In general, most gases do not expand upon heating.

Question

Quizplus · Accepted Answer

I and II are correct because gases indeed have lower densities compared to liquids or solids and their densities can significantly change with temperature. Additionally, gases are compressible, allowing them to occupy smaller volumes under pressure. Statement III is incorrect because gases generally expand upon heating, which is a fundamental property of gases.
