Figure 1 shows a piston-cylinder device. Initially it is filled with the volume of 0.334713 m³ saturated water at 100°C with the quality (dryness fraction) of 0.4. Heat can be transferred through the cylinder wall between the water system and the surrounding. The surrounding temperature is 177°C. The system is expanded isothermally with the temperature at 100°C until the final volume is just three times the initial volume. In the process, the work done by the water is 85.7 k), and the kinetic and potential energy changes are negligible. Note: please select the closest answer since you might keep the different decimal. Temperature in Kelvin = Temperature in degrees Celsius + 273

Question as shown in the picture.

Figure 1 shows a piston-cylinder device. Initially it is filled with the volume of 0.334713 m³ saturated water at 100°C with the quality (dryness fraction) of 0.4. Heat can be transferred through the
cylinder wall between the water system and the surrounding. The surrounding temperature is 177°C. The system is expanded isothermally with the temperature at 100°C until the final volume is just
three times the initial volume. In the process, the work done by the water is 85.7 k), and the kinetic and potential energy changes are negligible. Note: please select the closest answer since you might
keep the different decimal. Temperature in Kelvin = Temperature in degrees Celsius + 273

Please do the last three questions (2, 3 and 4)! Thank you in advance! A seesaw that weights 45lbs and its 5m long is balanced on the fulcrum in the center. 1- Two children are sitting on opposite sides of each other on the seesaw. One child weights 50lbs and is sitting 0.7m on the left end. Where should the other child sit in order to be balanced on the seesaw if they weigh 42lbs? 2- Now, a third child wants to sit on the seesaw and weighs 30lbs and is sitting 1.25m in front of them and is closer to the fulcrum on the right side. What are the CW and CCW moment of the seesaw now? What is the net moment and direction? 3- Then, a fourth child wants to play on the seesaw and is on the left side of the plank in order to bring the system to equilibrium. How much does the child weigh (Calculate the pounds of force needed in order for rebalance?) 4- Now the fourth child leaves the other three children sitting on the plank.
