Question

Arrange the following substances in the increasing order of u termokrcukat firces of attraction

..........................salt,water,carbon dioxide

Answer 1

ANSWER
______________________________

We have to arrange them in increasing order of intermolecular forces.

Salt is Solid.
Water is Liquid
Carbon Dioxide is Gas.

Solids have highest intermolecular force of attraction and hence is rigid and compact. Liquids have lower intermolecular Space and hence can flow. Gases have lowest intermolecular force of attraction.

ANSWER -

Carbon Dioxide < Water < Salt

Answer 2

Hello Dear !

As Salt is a solid - It has the strongest intermolecular forces of attraction .

As water is liquid  - it has lower intermolecular forces of attraction than solids 

As Carbon dioxide is a gas - its particles have negligible forces of attraction 

So the increasing order of intermolecular forced of attraction is 

Carbon dioxide < water < Salt
