Question

comment upon the following rigidity compressibility fluidity filling a gas shape kinetic energy and density

Answer 1

Rigidity:-- it is a property shown by solid.it related to tendency of solid to resist any charges in their shape when an external force is applied.if enough force is applied then solid may break but don't change their shape. liquid and gas are not rigid.

Compressibility:--it means reduction of volume of the substance on applying pressure.solids and liquid are uncompressible. bcoz there is very empty space btwn the particle of solid and liquid.Gases are easily compressible.

Fluidity:-- its a property shown by liquid and gases. it means tendency to flow.it is reversed if rigidity.

Filling a gas container:--it can be filled with a large amt of gas when an external pressure is applied on a gas while filling.

shape:-- solid have definite shape but liquid and gas donot have definite shape.

kinetic energy:-- it is also known as energy of motion bcoz particles of matter always remain in motion, they have kinetic energy.solid have least kinetic energy bcoz molecules are bounded very close to each other,in liquid the are less tightly bound so they have more KI then solid,gas have more KI bcoz the molecules are very far form each other.(KI=kinetic energy)

Density:-- it means how compact a substance is .it is mass per unit volume. solid have small volume and greater density bcoz their molecules are tightly packed.gas and liquid have particales which can move freely so they occupy more volume and least density...

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.
