Define the following terms..
* Compressibility
* Fluidity
* Kinetic energy
* Diffusion
Rigidity: The property of solids being stiff and resist towards stress is called rigidity. In solids � Rigidity is very high. In liquids � lower than solids but higher than gases. In gases � very low
Fluidity: The physical property of a substance that enables it to flow is called fluidity. In solids � Very low In liquids � Higher than in solids but lower than in gases In gases � Very high
Compressibility: The property of substance that how much the volume of a gas can be reduced by the application of force is called compressibility.
Kinetic energy is the energy of motion, observable as the movement of an object, particle, or set of particles. Any object in motion is using kinetic energy: a person walking, a thrown baseball, a crumb falling from a table, and a charged particle in an electric field are all examples of kinetic energy at work.
Diffusion: the process whereby particles of liquids, gases, or solids intermingle as the result of their spontaneous movement caused by thermal agitation and in dissolved substances move from a region of higher to one of lower concentration
