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: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 ark it the brainliest
Explanation:on the basis of kinetic theory,solids have definite shape and fixed volume due their strong intermolecular force and small intermolecular space is small which make them hard and rigid.
On the basis of kinetic theory,liquids have fixed volume but not a fixed shape due to its weak intermolecular force of attraction and large intermolecular space between them , so the liquids easily move from their places but does not leave it so liquids have a definite volume.liquids take the shape of container.
On the basis of kinetic theory,gases neither have definite shape or volume due to weak intermolecular force and larger intermolecular space ..It leave it places from gases
So it do not have definite volume too.
Hope it helps..
