! Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A piston-cylinder device initially contains 1 kg saturated liquid water at 200°C. Now heat is transferred to the water until the volume quadruples and the cylinder contains saturated vapor only. The saturated liquid properties of water at 200°C 3 are vf= 0.001157 m³/kg and uf- 850.46 kJ/kg (Table A-4). Water mkg 200°C Q Determine the final temperature and pressure. (You must provide an answer before moving to the next part) The final temperature is The final pressure is °C. kPa.

6. If 8 lbs of a substance receives 240 Btu of heat at constant volume and undergo a temperature change of 150oF. What is the average specific heat of the substance during the process? (3 DECIMALS IN FINAL ANSWER PLS)
A frictionless, freely moving piston-cylinder assembly with a mass of 85 kg and a cross-sectional area of 0.05 m2 is located at an atmospheric pressure of 97 kPa. The initial volume of the piston is 8.9 liters and contains 0.008 kg of air. Then, the volume is halved with the heat transfer from the piston-cylinder assembly to the environment. According to this; a) Calculate the final pressure of the container (kPa) in (bar), and its temperature in (K),b) Boundary work (kj),c) Calculate the amount of heat transfer to the environment (kj).R= 0.287 kj/kg K, g=9.81 m/s 2 (You can use other data from Thermodynamic Tables, Table 17 for air.)
It is a hot day in Atlanta and you and your friends bought an ice cream maker. The unit consists of a bowl and a base that rotates the bowl around a stationary mixing paddle. The walls of the bowl contain an unknown mixture that absorbs heat from the ice cream. The bowl must be frozen (-20°C) before use. Unfortunately, your friends have lost the instructions and can't remember how long to operate the unit. You tell them not to worry since you have mastered energy conservation problems and can calculate the amount of time required to freeze the ice cream. Looking at the box, you find the specifications for the unit: a) Inner surface area of freezing bowl: 600 cm2; b) Heat transfer coefficient for bowl:h = 0.025 J / (cm2 s .°C); c) Power required to stir the bowl (100% efficiency):25 W; d) Amount of ice cream mixture added: 1 kg; e) The rate of heat transfer is between the bowl and the milk. You know that solutes lower the freezing point of water. Assume that the freezing point is…
