Water in a 5-cm-deep pan is observed to boil at 98oC.At what temperature will the water in a 40-cm-deep pan boil?Assume both pans are full of water. Use 1000 kg/m3 as the density of water. Please give your answer in oC. You will need to assume that phase change only takes place on the bottom surface of the pan. Please start by finding the atmospheric pressure for the 5-cm-deep case. Then find the pressure at the bottom of the deeper pan.

solve correctly ,important.
wo springs with same spring constant are installed in a massless piston/cylinder with the outside air at 100 kPa. If the piston is at the bottom, both springs are relaxed and the second spring comes in contact with the piston at V = 2 m3. The cylinder contains ammonia initially at -2°C, x = 0.13, V = 1 m3, which is then heated until the pressure finally reaches 1200 kPa. At what pressure will the piston touch the second spring? Find the final temperature and the total work done by the ammonia.
As shown in the figure below, you have a system including a Polyethylene vessel with mass Myessel = 0.229 kg. The vessel contains water with mass Mwater = 0.399 kg. Both the vessel and water are initially at a temperature of 54.6 degrees Celsius. You add steam into the system. The steam has an initial temperature of 167.4 degrees Celsius and a mass of Msteam = 10.9564 kg. The system will reach equilibrium with all the water having vaporized at some final temperature above 100 degrees Celsius.

Let's consider a closed container. This has a glass sight that allows you to observe the liquid level. The container contains refrigerant 134a at 20 ° C. A dough extraction is carried out from the bottom at a very low rate, the temperature remains constant throughout the process. If the area of the container is 0.05m ^ 2 and after liquid extraction the level drops150 mm, determine the mass of refrigerant that came out. see img
