How do forces between particles in solids compare to forces in the other states of matter?

In liquids the particles are loosely packed and in gases it is very loosely packed.

Explanation:

The average kinetic energy of a particles is greater in gases to overcome the forces.

In solids it is very less kinetic energy and it is very difficult to  overcome the forces between the particles.

Gases are less thick and solids are progressively thick.

Hence the particles are in fixed position and it is tightly packed in a solid.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.

i believe the answer is three water molecules
