For either a monatomic ideal gas or a high-temperature Einstein solid, the entropy is given by Nk times some logarithm. The logarithm is never large, so if all You want is an order-of-magnitude estimate, you can neglect it and just say

- For one component gas that is confined in a box with volume V. We can get the entropy of the gas as S= Nk, in- where N is the total a² number of atoms, a is the radius of the atom. Can you guess how it is obtained?arrow_forwardFor one component gas that is confined in a box with volume V. V We can get the entropy of the gas as S = Nk, In where N is the total number of atoms, a is the radius of the atom. Can you guess (or work out) how it is obtained?arrow_forwardThe temperature in the deep interiors of some giant molecular clouds in the Milky Way galaxy is 50 K. Compare the amount of energy that would have to be transferred to this environment to the amount that would have to be transferred to a room temperature environment to bring about a 7.7 J/K increase in the entropy of the universe in each case.

- A highly non-ideal gas has an entropy given by S=aNU/V, where the internal energy, U is a function of T.Find the pressure, the expression for the heat capacity at constant volume, and the chemical potential.arrow_forwardNow, let's use this property of logarithms to learn something about the number of microstates available to a molecular system. The absolute entropy of a system is related to the number of microstates available to it via Boltzmann's formula S = kB In W. If a system containing one mole of an ideal gas has an entropy of 167.7 J/K, how many microstates does it have? Report the order of W, as we have defined it above, and you should use scientific notation, 1.23E45, and report 3 (three) significant figures.arrow_forwardWhat is the entropy S of this system at a given temperature T, asT→∞, and T→0. We expect the entropy S to be 0 at T= 0. Does entropy increase as the temperature T increases?arrow_forward

The entropy of the solid is ______ kB.(b) What is the entropy of an Einstein solid in a macropartition that contains 9 ×10 e690 microstates? Express your answer as a multiple of kB. The entropy of the solid is 1590.92kB.arrow_forwardProblem 1: Describe a situation in which the entropy of a container of gas is constant. In other words, come up with your own problem where the answer is that AS = 0.arrow_forwardThe molar heat capacities of gases are not perfectly constant, as we've assumed, but increase slowly with temperature. An empirical formula for the molar heat capacity at constant volume of nitrogen is Cv = (20.6 - 1.6 × 10¯³T +8.0 × 10¯67²) J/mol K, where T is in K. What is the entropy increase of the gas if 5.0 g of nitrogen in a rigid container are slowly heated from 300°C to 500°C? Express your answer with the appropriate units.arrow_forward
- One way to "derive" the thermodynamic definition for entropy is simply to recognize that its thermodynamic definition must be a state function, and all thermodynamic state functions are worthy of giving a special name and carry special meaning. a) Starting with the First Law of Thermodynamics (expressed either of 2 ways) AU = q + w du = dq + dw show all the steps and assumptions/conditions required to arrive at the new expression below, which includes the definition of entropy: AS - arev AU T T - nRln () arev must be state function. b) Using your result from part (a), explain why T To be explicit, explain why entropy must defined by (P, V, T) alone, and any change between the same 2 states, (P₁, V₁, T₁). and (P2, V2, T2), regardless of path, will give the same change in entropy.arrow_forwardThe molar heat capacities of gases are not perfectly constant, as we've assumed, but increase slowly with temperature.
