There is 1 mole of an ideal gas, and it goes from (p₁‚½‚T) to V₁₂ = 2½‚Ã₂ = through an irreversible process, and we set the specific heat 2V₁‚T₂ =T₁, capacity at a constant value, and try to figure out the change of the entropy in two ways.<

Krypton is compressed adiabatically in a closed system from initial pressure P1 = 1 bar, T1 = 9 oC to P2 = 9 bar. Due to irreversibilities there is an entropy generation equal to 5 J/(mol K).  Calculate the temperature at the end of the compression. Report your answer in units of oC. Assume krypton to be an ideal gas with CP = 2.5 R, where R is the molar gas constant with value 8.314 J/(mol · K).

A system consisting of 0.20 mol of supercooled gaseous water (95°C, 1 bar) partially condenses to liquid water; the process is done adiabatically at constant pressure.         At equilibrium, what is the temperature of the system? How many moles of gaseous water have condensed? Calculate the entropy change for the process.

An adiabatic steam turbine in an electric power plant is designed to accept steam at 5000 kPa and 600°C and discharge the steam at 101.3 kPa. a) What is the exit temperature of the steam and the work produced (per kg of steam) if the turbine operates adiabatically and reversibly? b) If the turbine operated adiabatically but irreversibly, with an isentropie efficieney of 80 %, what would be the exit temperature and the work produced (per kg of steam)? c) For part b, what is the entropy generation Sa?

Current Attempt in Progress * Your answer is incorrect. A rigid tank whose volume is 4 m³, initially containing air at 1 bar, 295 K, is connected by a valve to a large vessel holding air at 6 bar, 295 K. The valve is opened only as long as required to fill the tank with air to a pressure of 6 bar and a temperature of 350 K. Assuming the ideal gas model for the air, determine the heat transfer between the tank contents and the surroundings, in kJ. Qcy F i 879.84 eTextbook and Media kJ

PROBLEM 9. A bottle of milk was taken from a refrigerator and put in a bowl of hot water to warm. According to Newton's empirical law of cooling, change of temperature of the milk in the bottle M(t) and change of temperature of water in the bowl W (t) can be described by the differential equations dM dt = -k, (M – W) dW dt :-k2(W – Ta) – k3( – M), where t is time (in minutes), Tą is the ambient temperature, k, = 0.1, k2 = 0.03, and kg = 0.18 are constants of proportionality. The temperature in the refrigerator is 5°C, the room temperature is 20°C and the initial temperature of the water in the bowl is 80°C. a) Find the solution of the nonhomogeneous system X(t)=X.(t) + Xp(t) if the particular solution Xp(t) is given by: 20 20 b) Find the temperature of milk and water as function of time. c) Find the values of W (t) and M(t) when t → o.

Give a specific example of a system with the energy transformation shown. In the question, W is the work done on the system, and K, U, and Eth are the kinetic, potential, and thermal energies of the system, respectively. Any energy not mentioned in the transformation is assumed to remain constant; if work is not mentioned, it is assumed to be zero. W → ΔEth
