Question

Solids are generally .(rigid/soft)

Answer 1

• There are different states of matter i.e. solid, liquid and gas which have different properties.
• These properties are given in the table below:

Property	Solids	Liquids	Gases
Interparticle space	the least space between particles	intermediate space between particles	very large space between particles
Intermolecular attraction	strongest	intermediate	least
Shape	fixed shape	no fixed shape	no fixed shape
Volume	fixed volume	fixed volume	no fixed volume
Nature	rigid	fluid	highly fluid
Kinetic energy	least kinetic energy	intermediate kinetic energy	very high kinetic energy
Density	very high density	less density	least density
Compressibility	least compressible	more compressible	highly compressible

• The intermolecular forces in a solid are very strong, due to which molecules hold each other very strongly and resulting in a fixed shape.
• Hence, Solids are rigid.
