energy and density.
Answers
Answer:
Rigidity- The tendency of a substance to maintain their shape when subjected to an external force.
Compressibility- It means the contraction in the volume of a substance under the applied pressure. Liquid and gas are compressible because they have empty space, but solid does not.
Fluidity- Tendency of a particle to flow is known as fluidity. Liquids and gases can flow.
Filling of a gas container- The gases can fill the container with a large amount when we applied external pressure.
Shape- Solids have fixed shape and boundaries. Liquid and gases have no fixed shape and definite boundaries.
Kinetic energy- The energy possessed by particles due to their motion is known as kinetic energy. Gas has maximum kinetic energy as they have more random motion.
