Question

differentiate among solid, liquid, gas​

Answer 1

Particles in a: gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.

Solids vs Liquids vs Gases

Characteristics of Solids:


1. Volume: Definite volume, as intermolecular forces between the constituent particles are very strong.

2. Diffusion: Can diffuse into liquids.

3. Compressibility : Negligible

4. Rigidity or Fluidity : Very rigid and cannot flow

5. Density: High

6. Shape: They have a definite shape

7. Kinetic energy of particles at a given temperature: Least energy

8. Interparticle space: Least

9. Interparticle force of attraction: Very strong

10. Intermolecular forces: Strong enough to hold the constituent particles in fixed positions.

11. Arrangement of molecules: Packed in definite pattern so they possess a definite geometry.




Characteristics of Liquids:

1. Volume: Definite volume, as intermolecular forces between the constituent particles are strong.

2. Diffusion: Diffusion is higher than solids.

3. Compressibility: Negligible

4. Rigidity or Fluidity: Less rigid and can flow easily.

5. Density:Moderate

6. Shape: They do not have a definite shape.

7. Kinetic energy of particles at a given temperature: Higher than solids

8. Interparticle space: Lesser

9. Interparticle force of attraction: Less strong

10. Intermolecular forces: Strong enough to hold the constituent particles in aggregation within the bulk but not in  fixed positions.

11. Arrangement of molecules: Packed weak in comparison to solids, shape not fixed.



Characteristics of Gases:

1. Volume: No definite volume, as  intermolecular forces between the constituent particles are weak.

2. Diffusion: Highly diffusible as particles move randomly at high speed.

3. Compressibility: High

4. Rigidity or Fluidity: No rigidity and can flow most easily.

5. Density: Low

6. Shape: They do not have a definite shape.

7. Kinetic energy of particles at a given temperature: Maximum energy

8. Interparticle space:More than others

9. Interparticle force of attraction:Weak

10. Intermolecular forces: Extremely low, so that the constituent particles are free to move in a continuous random motion.

11. Arrangement of molecules:Packed very poorly so they fill the container, no definite shape.
