Question

Q6. Arrange the following in the order of: (a) Force of attraction (b) Intermolecular space.
Iron nail, Kerosene oil and Oxygen gas. Give reasons.​

Answer 1

Explanation:

Iron nail

FOA: high

IMS:low

KEROSENE OIL

FOA:low

IMS: high

Oxygen gas

FOA: very low

IMS: very high

FOA( force of attraction)

Oxygen gas <kerosene oil < Iron nail

IMS(Intermolecular space)

Iron nail<kerosene oil<Oxygen gas

Answer 2

Solid has most attraction of forces followed by liquid and then gas.

This is why solid is most dense, then liquid and then gas.

Gas has most intermolecular space, followed by liquid and then gas.

This is because of intermolecular attraction between molecules.

The more intermolecular attractions, the less is intermolecular space.

Iron nail is solid, kerosene soil is liquid, and oxygen is a gas.

So,

Force of attraction

Iron nail > Kerosene oil > Oxygen

Intermolecular spaces

Oxygen > Kerosene oil > Oxygen
