As an experiment, you plan on adding 1.5kJ of heat to an insulated container of monatomic Argon gas. To make sure you don’t melt anything, you need to make a prediction for the temperature change the gas will undergo. Use what you have learned and the Particle Model of Thermodynamics to fill in the chart below for this experiment and make a prediction for the temperature change. Show all work in the space below. For credit you must clearly show how you arrive at you final prediction. 1.5kJ->Ar (5 moles) Value (w/units if needed) E th E th + E B =Q+W , so: 1.5kJ Modes/Molecule (3 KE trans modes) : 3 modes/molecule Total Modes 3modes/atom*(5N A )= 9.03x10 24 modes Molar Heat Capacity C vn ½ R (3) = 12.46 J/(K mole)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
