Question

Define Rigidity, Compressibility, Fluidity, and Kinetic Energy.​

Answer 1

Answer:

1. RIGIDITY - it is the property of matter especially solid through which they can maintain their shape against external force.

2. Compatibility - it is a property of gases . On applying high pressure the volume of gas decreases.

3. Fluidity - it is the property of gases and liquids by which they can flow. Liquids can flow

but gases can flow easily than liquids.

4. Kinetic energy - Gases have maximum kinetic energy among three states of matter. The constituent particles of matter are in constant motion.kinetic energy increases with the rise in temperature and vice - versa.

KINETIC ENERGY = 1/2 mv², where m is the mass of the particle and v is the velocity of the particle.

Answer 2

1. rigidity: rigidity is the property of structure that it does not bend or flex under an applied force. It is opposite of flexibility.
2. Compressibility: compressibility is a measure of how much a given volume of matter decreases when placed under pressure.
3. fluidity: it is a property of matter which defines its nature to flow from one place to another. Gases has high fluidity.
4. kinetic energy: kinetic energy is energy possesses due to its motion.
