Consider 4.00 mol of an ideal gas with a constant‑volume molar specific heat of 12.5 J/(mol·K), an initial temperature of 26.8 ∘C, and an initial pressure of 5.710×104 Pa. The state of the gas is then changed to a final temperature of 48.1 ∘C and a final pressure of 3.090×104 Pa. What is the change in the entropy Δ? of the gas during this process? The gas constant is 8.31 J/(mol·K).
Suppose we place 47 g of ice at 273 K in contact with a heat reservoir at 309K. Heat energy spontaneously flows from the reservoir to the ice. Find the change in entropy (J/K) of the universe when the whole ice has melted to water at 273 K. Answer:
A vessel has two identical compartments (e.g. left and right), but gas molecules can go from each compartment into the other. (a) Initially there are 12 molecules in the left compartment and 0 molecules in the right compartment. Finally there are 6 molecules in the left compartment and 6 molecules in the right compartment. What happens with the total entropy of the gas in such a process? (b) Is it possible that the gas can go spontaneously from 6 molecules in the left compart- ment, 6 molecules in the right compartment to 12 molecules in the left compartment, 0 molecules in the right compartment?
70 moles of a certain substance (MW = 45 g/mol), when heated at constant pressure from 60 ⁰C to 75 ⁰C, results to 170 J/K change in entropy. Determine the specific heat capacity of the substance (in J/g-K).
A large factory furnace maintained at 170 ∘C at its outer surface is wrapped in an insulating blanket of thermal conductivity 5.50×10−2 W/(m⋅K) which is thick enough that the outer surface of the insulation is at 43.0 ∘C while heat escapes from the furnace at a steady rate of 140 W for each square meter of surface area. By how much does each square meter of the furnace change the entropy of the factory every second?
(a) What is the unit of "specific entropy"? Is it an extensive property? (b) What is an isentropic process? Please give an example. (c) Explain the increase of entropy principle.

Consider the adiabatic free expansion of n moles of an ideal gas from volume V₁ to volume V2, where V₂ > V₁. [Hint: check lecture 19, chapter 5.6, process number 5. Note that such a process happens quasi-instantaneously, thus, it is irreversible.] (1) Calculate the change in entropy of the gas. (2) Calculate the change in entropy of the environment. (3) Evaluate the total change in entropy (AS = ASgas + ASenv.) for 1 mole, with V₂ = 2V/₁.

A box contains 100 gas molecules all released on the left side of the box. What is the initial entropy of all the gas molecules on one side? You can calculate the number of microstates (left/right distribution of molecules) possible by the equation W = N! / ( nL! * nR!,) where N is the total number of molecules and nL is the number on the left and nR is the number on the right. What is the entropy of the most disorganized distribution of gas molecules?
A block made of cobalt with a mass of 0.80 kg is heated to 850°C, then dropped into 5.00 kg of water at 10°C. What is the total change in entropy (in J/K) of the block-water system, assuming no energy is lost by heat from this system to the surroundings? The specific heat of cobalt is 420 J/(kg · K), and the specific heat of water is 4,186 J/(kg · K). (Hint: note that dQ = mcdT.)
