Question

Give reasons: i) Gases do not settle at the bottom of the vessel.

a) Gases are lighter than liquids.
b) Gases have higher density than liquids.
c) Gases have lower density than solids.
d) Gases have no mass.

Answer 1

Gases do not settle at the bottom of the vessel because they have a lower density than liquids and solids, and the energetic particles move freely, filling the entire space available.

Step-by-step explanation:

The reason gases do not settle at the bottom of the vessel is because gases have a lower density compared to solids and liquids, which causes them to spread and fill the entire container. Additionally, gas particles have enough energy to overcome intermolecular interactions, allowing them to move about randomly in space and not be bonded to neighboring atoms. This explains why gases do not have a definite shape or volume and cannot be easily compressed.
