3. Explain the following on the basis of kinetic theory
of matter.
(a) Solids have a definite volume and definite
shape.
(b) Liquids have a definite volume, but no definite
shape.
(c) Gases have a no definite volume and no
definite shape
Answers
Answer:
(a)Three states of matter exist – solid, liquid, and gas. Solids have a definite shape and volume. Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.
(b)In a liquid, the particles are still in close contact, so liquids have a definite volume. ... However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.
(c)Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume either. The change from solid to liquid usually does not significantly change the volume of a substance.
Explanation:
this is your answer, please thanks me and mark me as brainlist.
Answer:
(a) Solids have a definite volume and definite
shape.
(b) Liquids have a definite volume, but no definite
shape.
(c) Gases have a no definite volume and no
definite shape
Explanation:
this is bcoz of intermolecular spaces and forces between them.
