Which of the following statement about the force of attraction between the particles is/are correct? The force of attraction between the particles of the same substance is known as cohesion. The force of attraction is maximum in the particles of solid matter and minimum in the particles of gaseous matter.
Procedural cohesion is similar to sequential cohesion, except that with procedural cohesion _____
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?

Two identical particles have to be distributed among three energy levels. Let rB, rF and rC represent the ratios of probability of finding two particles to that of finding one particle in a given energy state. The subscripts B, F and C correspond to whether the particles are Bosons, Fermions and classical particles, respectively. The rB : rF : rC is equal to
