Thermodynamics Question: Begin with a rigid closed cylinder with fixed 1 L volume at 50 atm pressure and 350 K temperature. Plot the pressure as a function of temperature, as the temperature falls to 200K.  Assume the contained fluid is 100% nitrogen – assume SRK EOS

Hi tutor, please answer in 30 minutes with explanation.

NEED IN RUSH PLEASE THANKS  IN ADVANCE

i need the answer quickly

ans: 0.01925kg, 0.7123kg, 1.886kPa Use gas laws

(Practice Only) A rigid (constant volume) balloon is inflated at sea level, then submerged underwater, doubling the pressure on the gas. Explain how the temperature changes. A mixture of saturated water has quality x = 0.75 at temperature 90°C. Determine the average specific volume, v. For water at 60°C and 500 kPa, determine the internal energy, u, quality, x, and phase description. Explain how answer.

Pre-lab 8: Cold Engine The experimental setup for this week's lab consists of a syringe connected to a metal can (reservoir), a cold bath (water - ice mixture) and a "hot" bath (water at room temperature). A schematics of the syringe - reservoir system is shown below. Plunger of mass m Filled with gas (air) Syringe of volume Vcor VH - Volume Vo includes tube + Metal can -Metal can submerged in water of temperature Тс or TH. Tube Stopper Figure 1: Schematic of the syringe - reservoir system. The syringe is essentially a glass cylinder fitted with a movable piston (plunger). The markings on the syringe indicate the volume of gas in the syringe, but do not include the additional, unknown volume, Vo, in the gas can and tubing.

Psychrometric process A room has dimensions of approximately 10m x 10m x 3m. Assume the air inside the room to be at T= 20 oC, P = 100 kPa, Relative Humidity = 50% a. If all of the water vapor in the air of the room could be converted to liquid at the same temperature, what is the volume of the liquid (mL)? b. If the room temperature were slowly cooled without changing the composition of air, at what temperature would you expect to see condensation occurring (oC)?

2. Find: a. hof steam at saturation pressure of 0.015 MPa and temperature of 800 K b. v of subcooled liquid at saturation pressure of 1.44 MPa and temperature of 17.5°C Use the sample table as reference for your solution in number 2 Sample, find the enthalpy of superheated steam at 1.45 MPa and 515°C.
