A piston-cylinder arrangement contains water at 110°C, 85% quality with a volume of 1 L. What is the initial mass, in grams? The system is heated, causing the 150-mm-diameter piston to rise and encounter a linear spring with k = 800 kN/m. Calculate the specific internal energy (kJ/kg) at this instant knowing that the measured volume is 1.65 L. The heating continues and compresses the spring in the process. When the piston encounters the stops, the pressure is 200 kPa. What is the temperature (in °C) and entropy (in J/K) at this point? Heating continues until the pressure reached 300 kPa. What is the volume, in L at this instant? Illustrate the process in separate P-v and T-v diagram. Note:1000 L = 1m3. Hint: Draw the FBD of the piston in each state.
A gas is compressed inside a compressor’s cylinder. Whenthe piston is at its bottom dead center, the gas is initiallyat 10 psig, 65°F, and 10.5 in3. After compression andwhen the piston is at top dead center, the gas is 180°Fand occupies 1.5 in3. What would be the new pressure ofthe gas in psig?
A piston-cylinder arrangement contains water at 112°C, 84% quality with a volume of 0.98 L. What is the initial mass, in grams? The system is then heated, causing the 150-mm-diameter piston to rise and encounter a linear spring with k = 800 kN/m.

The frictionless piston and cylinder contain 1 kg of water. The initial pressure and volume are each pressure of 100kPa 0.25 m^3 (state 1). The system was gradually heated and when the volume of water in the cylinder became four times the initial volume (state 2), the piston was fixed and heating was continued until the water pressure reached 300 kPa (state 3). (1) Find the final temperature in the cylinder (2) Find work during this process (3) Find the amount of heat transfer during this process. Try to approximate this process on a P-v diagram.

A mass of air (molecular mass equal to28.97 g/mol) at 150 kPa and 27 is contained in africtionless piston-cylinder device. At the initial state,the piston is resting on a pair of stops and the totalvolume of occupied by the air is 400 L. The mass ofthe piston is such that a 350 kPa pressure is neededto move it. The air is now heated until its volumehas doubled. Draw the process on the PV diagram.Determine: (a) the final temperature; (b) the workdone by the air; and (c) the total heat added into thegas.

There is an 500g container made out of aluminum holding 300g of water. The Water and Aluminum have reached thermal equilibrium at 40 degrees Celsius. A 200g block of iron at a temperature of 0 degrees Celsius is later dropped into the water. Using the specific heat for water=4180J/kg/C. The specific heat for aluminum is 900 J/kg/C. The specific heat for iron is 450 J/kg/C. The final temperature of the three materials will be degrees celsius. The thermal energy of the water changes by Joules.

In an attempt to cool this system, a small block of ice at 0°C is added to the water. a. Determine the exact mass of ice needed to melt (giving up its latent heat of fusion) and bring the water and beaker temperature down to 0°C. b. If the ice block has a mass of 100 g, determine the final temperature of the system. If it turns out that Tf = 0°C, determine how much ice remains unmelted. c. Repeat your calculations for 50 g of ice.
