PHYS 251 Homework 3 So Much Capacity! 1 of I l) The data on the plot below was taken from system containing 2 mol of argon gas. Thermal Energy of 2 mol of Ar f" o .'" a 7" u , 3? >- 9 U I: LLI '5 E16 .C . E : l U 4.. E 300 Tempu ratu re (K) For each show all of your work and provide annotated explanations of your reasoning. a) On a thermal energy vs. temperature plot (like the one above) is it possible to have a non-zero y- intercept? Explain. b) Determine the heat capacity of the system. c) Two additional mols of argon gas is added to the system. What effect does that have on the heat capacity of the system? d) How much heat is required to raise the temperature of the original system from 290K to 390K? e) If the original 2 mols of argon gas [atomic mass = 40g/mol] was replaced with 2 mol of neon gas [atomic mass 2 20g/mol], sketch a plot of the thermal energy vs. temperature like the one above over the same temperature range. 2. Mass matters or doesn't matter. It would seem that the issue of mass does matter, at least in that it is still a heavy issue (see what I did there?) We can talk about the mass of a system of particles or we can talk about the mass of the particles in the system. a) What affect does changing the mass of the system (without changing the particle type) have on the heat capacity? On the molar specic heat? On the mass specic heat? Explain each. b) What affect does changing the mass of the particles in the system (would require changing the particle types only) have on the heat capacity? On the molar specic heat? On the mass specic heat? Explain each. [Does this change the mass of the system as well?]
