:
(a) Distinguish between solids and gases on the basis of following parameters:
(i) Interparticle distance
(ii) Interparticle forces of attraction,
(iii) Compressibility
(b) Give two factors that determine the rate of diffusion of a liquid in another liquid.

​

Answer 1

B the factors are temperature of liquid and concentration of liquid ., hope it helps u . Pls mark as brainliest and thank me

Answer 2

The correct answers are given below.

(a). The solids and gases can be distinguished as follows, based on the given parameters.

(i). The average distance between particles in a substance is referred to as the interparticle distance.

• Since gas molecules are loosely packed compared to solid molecules, the interparticle distance is higher for gases than for solids.

(ii). The attraction between a substance's particles is known as the interparticle force of attraction.

• Because solid particle packing is more dense than that of gas particle packing, solids exhibit greater interparticle forces of attraction than gases.

(iii). Compressibility is a substance's capacity to have its volume or size reduced when pressure is applied.

• Solids cannot be compressed.
• A gas is easily compressible due to the void areas between its molecules.

(b). The two factors that determine the rate of diffusion of a liquid into another liquid are temperature and density.

• While it is inversely proportional to liquid density, the rate of diffusion is directly correlated with temperature.
• When the rate of diffusion increases, temperature also increases and density decreases and vice versa.
