Question

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​

Answer 1

Answer:

I can answer only the a part rn

Explanation:

(a) liquids have fixed volume because until and unless we decrease them their volume remains the same, and so the volume of liquids stays the same without disturbing it.

They don't have a fix shape because their molecules are really lightly packed and so they ain't strong enough to maintain a fix shape shape.

I hope this one is clear :)

Answer 2

Explanation:

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.

b)The atoms, ions, or molecules that make up the solid or liquid are very close together. There is no space between the individual particles, so they cannot pack together. The kinetic-molecular theory explains why gases are more compressible than either liquids or solids.

c) Two factors which determine the rate of diffusion of a liquid in another liquid are: Temperature – higher is the temperature, greater is the rate of diffusion. Density- More is the density of one liquid, lesser is the rate of its diffusion in other liquid.

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)Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles.
