Question

on the basis of the Kinetic Theory of Matter explain why (a) solids have a fixed shape and a fixed volume. (b) liquids have a fixed volume but not a fixed shape. (c) gases have neither a fixed volume nor a fixed shape.​

Answer 1

Kinetic energy is the energy of the movement of an object.

Explanation:a) Solids have a fixed shape and volume as their matters are tightly packed and their kinetic energy is low so they are rigid ,have a fixed shape and volume .

b)Because the particles in liquids are very close together (barely further apart than in solids) liquids do not easily compress, so their volume is fixed. Gases can also flow, so occupy the shape of their whole container. They do not have a fixed shape.

c)As gases have more free space than the other 2 so the have the most amount of kinetic energy. Their matter moves freely in all directions so it does not have a fixed volume and shape.

If this is the answer than mark it brainliest

Answer 2

a) Solids have a fixed shape and a fixed volume because they have strongest inter molecular force of attraction and due which inter molecular space is very less.

b) Liquids have a fixed volume but not a fixed shape because their inter molecular force of attraction is less than the solids due to which inter molecular space is more than solids.

c) Gases have neither a fixed shape nor a fixed volume because their inter molecular force of attraction is the least and due to which inter molecular space is very large.

Hope it helps you
