- This is for my thermodynamics review problems can you show the full solution... 7. Water vapor at 100 kPa and 150°C is contained in a rigid vessel. At what temperature will the vapor start to condense when the container is cooled slowly? How much heat will have to be removed per kilotram in this cooling process? Ans. 95.68°C, -81.4 kJ/kgQ5:0 eg of water at 47-82 is heated under constant pressure ot 13.7 bax until it is converted into Siteam withe 111 of Supor- heated. Determine the quanti ty of heat Supplied during Superheating and the total heat [268 1g » 2852k9]Which of the following is the equivalent heat transferred of gas undergoing isometric process? Select the correct response: Change in internal energy Change in entropy Work non-flow Change in enthalpy
- What is the difference between specific internal energy and specific enthalpy in first law of Thermodyanamics and when should i use which? From what i understand so far for constant pressure process, we use q-w=h2-h1 and constant volume process, we use q-w = u2-u1. But this isnt the answer i am looking for.Calculate the heat capacity of a gas sample from the following information: The sam- ple comes to equilibrium in a flask at 25°C and 121.3 kPa. A stopcock is opened briefly, allowing the pressure to drop to 101.3 kPa. With the stopcock closed, the flask warms, returning to 25°C, and the pressure is measured as 104.0 kPa. Determine Cp in J mol- K- assuming the gas to be ideal and the expansion of the gas remaining in the flask to be reversible and adiabatic.Mr Luda wants to understand further about a newly created gas. The gas is initiallyat a pressure of 90 kPa, volume of 1.258 m3 and temperature of 10°C (State 1).The gas undergoes a 3-step process in which it is first compressed isothermally toa pressure of 400 kPa and volume of 0.283 m3 (State 2), then expanded at constantpressure back to its original volume (State 3). Finally, the gas is returned to itsoriginal State 1 by cooling at constant volume.a) Sketch the cycle of this system on a P – V diagram.b) Calculate the work done (in kJ) for each process step.c) Determine the total work done for the three-process cycle.d) State whether the work done is on or by the system.
