Unformatted text preview: like PE or KE, translational or. .. etc.). modes/atom for O 2 modes/atom for Au b) If Marta has the same setup with the same substances, but at 1000 K, considered a high temperature for activating modes, how will your answer to part a) change? Explain. 2. (30%) (Now suppose Marta uses the same setup room temperature for Question 1, but substitutes neon (Ne), a monatomic gas, for the nitrogen, so that the number of modes per atom in the gas changes from that of part 1 a). If Marta has 3 moles of Ne and 2 moles of Au, determine which of the two is easier to heat up to 1000 K (Hint: First determine how many modes per atom for each substance.) Show your work. 3. (15%) Marta’s friend, Rick, states that in general it's easier (takes less energy) to increase the temperature of O 2 gas than Ne gas. Do you agree? Explain....
