Which of the following gas samples possesses the largest internal energy? (Treat all gases as ideal; neglect vibrational contribution.)
Options:
Answer:
C
Solution:
U of an ideal gas depends only on n and T. (a) 3/2(4)R(300) = 1800R. (b) 3/2(3)R(1000) = 4500R. (c) n = 280/28 = 10 mol, diatomic: 5/2(10)R(300) = 7500R. (d) n = 1 mol: 5/2(1)R(1000) = 2500R. The largest is (c).
