Question

A b) Comment
upon
the following, rigidity. compressibility,
container & shape, inergy
fluidity filling a gas
container,shape,kinetic energy and density​

Answer 1

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.

Answer 2

Rigidity: The condition which do not alters the shape of solids.

Compressibility: Compressing particles of gases

is called compressiblity.

Filling a gas container: In the laboratory, after the preparation of gases, they are collected in gas jar. This is called filling a gas container.

Fludity: Fluidity means flowing of liquids freely.

Shape: Things are in which form is called shape.

Kinetic energy: The energy possessed by moving body is called kinestic energy.

Density: Density is the mass per unit.
