Difference between Properties of Solid Liquid and Gas

Matter is found in three physical states – Solid, Liquid and gas in normal conditions.

We will discuss the difference between the properties on the basis of shape, volume density and other level etc. This topic is useful for class 9 and for others.

Table of differences between Properties of solid liquid and gas

Property	Solid	Liquid	Gas
Shape	Definite	Indefinite	Indefinite
volume	Definite	Definite	Indefinite
Inter particle attraction force	Very strong	Weak	Very weak
Density	High	Lesser than  solid	Very low
Inter-particle  space	Particles closely picked	Loosely packed	Very loosely packed
Compressibility	Negligible	Very small	High
Rigidity	Very hard and rigid	Less rigid	Least rigid
Fluidity	Negligible	Have fluidity	Highly fluidity
Diffusion	Negligible	Slow	Very fast
Kinetic energy	Very low	High	Very high
Particle motion	Particles vibrate	Particles move	Particles move very fast

 

 Frequently Asked Questions

   1. Why solids do not show diffusion?

Ans – Constituent particles are closely packed due to strong attraction force so solid do not show diffusion.

   2.What is fluidity?

Ans – The tendency of flowing is called fluidity.

   3.What is the common property between liquid and gas?

Ans – Both liquid and gas have fluidity.

   4.What is diffusion?

Ans – The movement of particles from region of higher concentration to region of lower concentration.

   5.What is matter?

Ans – Anything that occupies space and has mass is known as matter.

   6.How many physical states of matter is found in ordinary conditions?

Ans – A matter can be found in three physical states –(i)  solid (ii) liquid (iii) gas
