Question

seperate the following substances in groups of high and low intermolecular force. ice ,sulphur vapour,nitrogen,sugar,copper,air,salt,plastic.

Answer 1

Answer:

Explanation:

High.

Ice sugar salt plastic copper

Low

Sulphur vapour air nitrogen

Answer 2

High molecular forces: Sugar, plastic, Ice, salt and copper.

Low molecular forces: Air, sulphur vapour, nitrogen.

Explanation:

Forces exists between two atoms of molecules present in the substances.

Solid substances have high inter molecular forces because atoms are tightly packed together in the solid state.

The given compounds are as follows.

Air, sulphur vapour, nitrogen, Sugar, plastic, Ice, salt and copper.

Sugar, plastic, Ice, salt and copper are present in solid state, therefore, it have high inter molecular forces.

Air, sulphur vapour, nitrogen have low molecular forces of attractions because those are present in gaseous form.
