In this discussion, you will briefly explain each of the four gas laws and apply an example as it happens in a refrigeration system. (Boyle’s, Charles’, Dalton’s, and the general law of perfect gases). In your contribution, also address the following: What makes matter change to different states? What type of energy do you think is the most important for the HVAC-R industry?

Need help with this engineering problem. Which unit could be used in the Ideal Gas law equation to get specific volume in ft3/lbm? absolute pressure in lbf/ft2, Temperature in °R and the gas constant in ft·lbf/lbm·°R absolute pressure in lbf/ft2, Temperature in °F and the gas constant in ft·lbf/lbm·°R absolute pressure in lbf/ft2, Temperature in °R and the gas constant in ft·lbm/lbf·°R barometric pressure in lbf/ft2, Temperature in °R and the gas constant in ft·lbf/lbm·°R gauge pressure in lbf/ft2, Temperature in °F and the gas constant in ft·lbf/lbm·°R

In a cylinder of an automobile engine, immediately after combustion the gas is confined to a volume of 53.0 cm³ and has an initial pressure of 3.60 × 106 Pa. The piston moves outward to a final volume of 300 cm³, and the gas expands without energy transfer by heat. (Assume the gas in the engine is diatomic with y 1.40.) (a) What is the final pressure of the gas (in kPa)? = 317.920813906 kPa (b) How much work is done by the gas in expanding (in J)? 238.559389571 J (c) What If? If the engine operates in an ideal Otto cycle and 0.0125 mol of fuel-air mixture is injected into the cylinder during the intake stroke, what are the temperatures (in K) at points A, B, C, and D of the cycle as shown in the figure?

* Your answer is incorrect. A piston-cylinder assembly contains 0.7 lb of propane. The propane expands from an initial state where p₁ = 60 lbf/in.² and T₁ = 70°F to a final state where p₂ = 10 lbf/in.² During the process, the pressure and specific volume are related by pv² = constant. Determine the energy transfer by work, in Btu. W = i 3.123 Btu
