Question

What is the difference between fluidity and rigidity?

Answer 1

Fluidity....... .If a substance can flow then it is called fluid. In fluids inter-molecular force of the matter is less. Fluids can flow. Temperature of fluids is higher than rigids. Sloids are least fluid. Liquids are fluid than solids but less than gases, which are most fluid............... Rigidity..........If a substance has a tendency to maintain its shape then it is calle rigid. In rigids inter-molecular force of matter is high.Rigids can not flow.Temperature of rigid matter is low. Solids are most rigid. Liquids are less rigid. Gases are least rigid

Answer 2

Answer: A substance which has tandency to flow. Due to large interparticle distance gases have highest fluidity..

Rigidity : it means tendancy to decrease the volume. When some outside force is applied. Gasses posses high compressibility.
