Which of the following statements about centrifugation are correct? Statement 1: Particles are separated from a solution according to their size. Statement 2: Particles are not separated from a solution according to their shape. Correct Answer True, False

Centrifugation is a process of separating substances which involves the centrifugal force. The particles are separated from a solution according to their size, shape, density, the viscosity of the medium and rotor speed.

Which of the following statement(s) is/are true? A. Shape: According to the type of matter, the shape changes depending on the location of the particles. For example, solids have a definite shape, whereas liquids acquire the shape of their vessel and, seen, gases have no shape. B. Filling a vessel of water: It is a property of matter, which decreases in volume under high pressure, and gas shows this property.

Which of the following statement is true? A. Firmness: According to the type of matter, the size of a substance depends on the position of its particles. For example, solids have a fixed shape while liquids acquire their vessel shape and gases have no shape. B. Size: This is the property of a substance in which its volume decreases under high pressure. This property is found in gases.
Which of the following statements is/are true? A. Rigidity: According to the type of matter, shape differs, depending upon location of particles. Eg, solids have definite shape while liquids acquire the shape of their container and gases, as such. don’t have any shape. B. Compressibility: It is the property of matter to allow a decrease in volume under high pressure and gases show this property.
The critical reasoning question is based on a short argument, a set of statements, or a plan of action. For each question, select the best answer of the choices given. The size of particles is directly linked to their potential for causing health problems. Small particles less than 10 micrometers in diameter cause the greatest problems, as they can get deep into the lungs and some may get into the bloodstream. One being exposed to such particles can affect both the lungs and the heart of a person. But there are particles that are causing environmental effects too, few of which are given below.  Which among the following below options does not talk about the effects of these particles on the environment?
