Question 1. A rigid container (think about what that means) is filled with a perfect gas (R = 200J/(kg•K)). The volume of the container is 0.8m3. The pressure reading on a gage attached to the container reads 108kPa and the temperature is 69ºC. Find the gage pressure of the gas in the container after the temperature is increased to 193ºC. Atmospheric pressure is 1bar.
Question 2. 0.0017-lbm of air/fuel mixture burns in a piston/cylinder device, releasing a total of 0.61Btu of heat. This occurs during an isometric process where the starting pressure is 71-psia and the starting temperature is 811ºR. Find the final pressure using an air-standard analysis of this process.
Question 3.? A piston/cylinder device compresses 23.2 grams of hydrogen adiabatically from a starting temperature of 39ºC and starting pressure of 109kPa absolute to a final pressure of 2,922kPa absolute. Determine the work for this process. Be sure to use the correct sign conventions with your answer.
Question 4.? Using the information provided with the previous problem, determine the heat added/rejected during the described process.
Question 5.? Determine the change in pressure for an adiabatic process using Argon that has an initial volume of 105-in3 and an initial pressure of 19-psia and a final volume of 19.1-in3.
