Differentiate the physical changes among the 3 phases or states of matter?

Answer 1

characterstics solid liquids gases

1) shape fixed not fixed not fixed

2)tnterparticle space least more than solid more than liquid

3)volume fixed fixed not fixed

4)density maximum less than solid less than liquid

5)compressiblity neglibile more than solid maximum

6)diffusion slow moderate fast

7)fluidity cannot flow flow flow

Answer 2

S. No.

Solid state

Liquid state

Gaseous state

1.

Definite shape and volume.

No definite shape. Liquids attain the shape of the vessel in which they are kept.

Gases have neither a definite shape nor a definite volume.

2.

Incompressible

Compressible to a small extent.

Highly compressible

3.

There is little space between the particles of a solid.

These particles have a greater space between them.

The space between gas particles is the greatest.

4.

These particles attract each other very strongly.

The force of attraction between liquid particles is less than solid particles.

The force of attraction is least between gaseous particles.

5.

Particles of solid cannot move freely.

These particles move freely.

Gaseous particles are in a continuous, random motion.

Answer 3

The physical changes among the three is that solid can touch it, liquid can feel it, and gas is the most s
