D. Neither A nor B
5. Boyle's law relates to which state of matter?
A. Solid state

D. None of the above

ANSWERS:

1. Ans. D

Explanation: Distillation is a procedure by which two liquids with different boiling points can be separated or it is a process in which the components of a substance or liquid mixture are separated by heating it to a certain temperature and condensing the resulting vapours.

2. Ans. C

Explanation: When the particles present in the fluid are so small that they crosses the pores of the filter sheet, so these particles are not separated by filter method. When these mixtures are rotated quickly, heavy particles sit down and the light particles remain above. This is centrifugation technique or we can say that Centrifugation is a technique used for the separation of particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed.

3. Ans. A

Explanation: A process by which molecules of a solvent tend to pass through a semi-permeable membrane from a less concentrated solution into a more concentrated one is known as osmosis.

4. Ans. B

Explanation: Two or more elements or compounds when mixed in any proportion so that the chemical properties of the components do not change, then it is called a mixture.

5. Ans. C

Explanation: Boyle's law, the pressure of certain quantities of gas on stable heat is inversely proportional to its volume.
