find and explain different activities to demonstrat
(a) liquid has fixed volume but it has no fixed shape
(b) compressibility of a liquid is higher than that of the solid but much smaller than compared to the compressibility of a gas
(c) diffusion of a liquid in another liquid
(d) diffusion of a solid in a liquid
(e) diffusion of a gas in a liquid
Answers
Answer:
Have to be shown by doing an activity?
Answer:
a) 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
d)If a solid is kept in contact with excess of solvent in which it is soluble, some portion of the solid gets dissolved. This process is known as dissolution of a solid in liquid, and it takes place due to the diffusion of solid particles into liquid medium.
e)when carbon dioxide diffuses into carbonated drinks then it shows diffusion of a gas into a liquid. As in liquids, molecules are held close due to slight more strong intermolecular forces of attraction as compared to gases. Hence, they take a little tie to diffuse as compared to gases.
