Section A contains 8.0 g of helium at 300 K, and section B contains 0.5 moles of an unknown gas at 400 K. When they reach thermal equilibrium, the unknown gas is at 329.41 K. Assume ideal gas behavior and no vibration for both gases. (a). What are the CV and Cp of the unknown gas?(b). How many degrees of freedom does the unknown gas molecule have?(c). What is the change in the total translational kinetic energy of the unknown gas molecules?
- Q1/ The ideal gas equation of state is given by: PV = nRT Where: P is the pressure (atm), V is the volume (L), 7 is the temperature (K), R=0.08206 (L atm)/(mol K) is the gas constant, and n is the number of moles. Real gases, especially at high pressures, deviate from this behavior. Their responses can be modeled with the van der Waals equation: nRT V-nb Where a and b are material constants. For CO₂ a 3.5924 L'atm/mol², and b=0.04267 L/mol. Calculate P from both equations for CO₂ gas with 40 values of V between 0.01 and 1.5 and display the results in: 1- Three-column table where the values of Vand both P are displayed in the first, second, and third columns, respectively. 2-Plot V versus both P in two different plots in the same figure with a solid line, black color, with circle marker.

The external pressure is constant at 1.00 atm. The initial temperature is 200K When the temperature is decreased by 64 K, by putting it in a lower temperature freezer, the volume will decrease, according to the Ideal Gas Law. Calculate the work for this process. Express your answer in J. The conversion factor between liter atmospheres and joules is 101.3 J = 1 L atm. The gas constant is 0.08206 (L atm)/(mol K). Molecular weight of Nitrogen is 28 g/mol W = The definition of mechanical work is: w -Pext(AV) where AV =…2C8H18 + 25O2 = 16CO2 + 18H2O. Find additional pressure from a 1.00g mass of octane. Volume is 1L. Compare additional pressure to initial pressure of 25 bar.
- p = 300kPa3. A gas contained within a closed piston-cylinder assembly undergoes three processes in series: Process 1-2: Constant volume from P₁ = 1 bar, V₁ = 4 m³ to state 2, where P₂ = 2 bar; Process 2-3: Compression to V3 = 2 m³, during which the pressure-volume relationship is PV = constant; Process 3-4: Constant pressure to state 4, where V4 = 1 m³; (a) Sketch the processes in series on P-V coordinates. (b) Evaluate the magnitude of work in kJ for EACH process. To make the unit consistent, you might need to convert the unit of pressure from bar to Pa.3 Why is it wrong to calculate (and report) a value for the quality of a compressed liquid or superheated vapor?
