A thermodynamics process is represented by the following h-s diagram. The process shown by 1 to 2a is most likely happens in Enthalpy 2b O Isentropic nozzle O Isentropic turbine O Isentropic diffuser O Actual compressor Entropy)

If you have a material that is initially hard and strong, would you expect it to cyclically harden or soften? What would be a way of characterizing how strong it must be initially to make your answer a bit more quantitative?

A 2.00 mol sample of an ideal diatomic gas is taken through a reversible cycle A → B → C → A as shown in the figure below. Process A → B is isothermal expansion. For the cycle, calculate: a) the work done by the gas, b) the heat energy added to the gas, c) the heat energy exhausted by the gas, d) the thermal efficiency, e) the change in entropy of the gas. f) Determine the efficiency of a Carnot engine operating between the same temperature extremes,           R = 8.314 J/mol K      Data at vertices for the above PV diagram are as follow: PA = 5.00 x 105 Pa, VA = 1.00 x 10 -2 m3,     PB = 1.25 x 105 Pa, VB = 4.00 x 10 -2 m3                   PC = 1.25 x 105 Pa, VC = 1.00 x 10 -2 m3
