Question

4. A gas cannot be stored in an open jar. Why?
5. Write three differences between solids liquids and gases
6. Define the following:​

Answer 1

Answer:

(4) No its not possible to keep / store gases in open container. Why? Because, when we compress gases into cylinders or containers then particles of gas exerts pressure on wall of container but due to lit the gas isn't allowed to escape.

(5) Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its container.

Answer 2

the intermolecular force is very less in gas atoms so they move freely around . 5) solids have high intermolecular force and less intermolecular space , they can be stored in bottles . liquids have less molecular and high intermolecular space compared to solids they change their shape acc to the container their in . gases have the least intermolecular force and highest intermolecular space they change shape acc to the container they re in
