Question

compare a block of wood water and air and the basis of the following 1 compressibility 2 particle motion

Answer 1

1.wood-(i)less compressibilty (ii)it is tightely packed so there particles can't move.
2.water-(i)intermediate compressibility (ii)it is losely packed so there particles can move.
3.air-(i)high compressibility (ii)it is freely movable

Answer 2

1)wood-negligible compressibility,water-medium compressibility,air-easily compressible
2)wood particles do not move freely,water particles move freely but don't go out of boundaries of container,air has very much kinetic energy
