Hexane, perfluorohexane and water are immiscible liquids and when placed in a graduated cylinder along with pieces of high-density polyethylene, polyvinylchloride and Teflon which are not dissolving in the given liquids, what can be seen in the cylinder has to be given. Concept Introduction: Buoyancy: It explains the floating nature of a substance in a fluid based on the densities of the substance and the fluid in which it is placed. If a substance with low density is placed in a fluid of more density, then the substance floats in that fluid. If a substance with high density is placed in a fluid of low density, then the substance sinks in that fluid.

Question

The table includes macrostates characterized by 4 energy levels (&) that are equally spaced but with different degrees of occupation. a) Calculate the energy of all the macrostates (in joules). See if they all have the same energy and number of particles. b) Calculate the macrostate that is most likely to exist. For this macrostate, show that the population of the levels is consistent with the Boltzmann distribution. macrostate 1 macrostate 2 macrostate 3 ε/k (K) Populations Populations Populations 300 5 3 4 200 7 9 8 100 15 17 16 0 33 31 32 DATO: k = 1,38×10-23 J K-1

Interpretation Introduction

Interpretation:

Hexane, perfluorohexane and water are immiscible liquids and when placed in a graduated cylinder along with pieces of high-density polyethylene, polyvinylchloride and Teflon which are not dissolving in the given liquids, what can be seen in the cylinder has to be given.

Concept Introduction:

Buoyancy:

It explains the floating nature of a substance in a fluid based on the densities of the substance and the fluid in which it is placed.

If a substance with low density is placed in a fluid of more density, then the substance floats in that fluid.

If a substance with high density is placed in a fluid of low density, then the substance sinks in that fluid.
