Introduction to statistical mechanics : Introductory video

Before watching the video read the questions below. As you watch the video try to answer them

Questions

    • Explain the meaning of the term microstate in statistical mechanics.
    • Explain what we mean by phase space when we use this term in statistical mechanics
    • Explain what we mean when we talk about accessible microstates in the context of statistical mechanics. For example explain the meaning of the following statement "if the system has a fixed total energy $E$ then only a subset of the microstates in phase space are accessible" by making reference to the energies of the accessible and inaccessible microstates.
    • State the principle of equal a priori probabilities
