Which of the following gas possess the largest internal energy?
Options:
Answer:
B
Solution:
For an ideal gas U depends only on n and T (pressure and volume do not matter). (a) U = 3/2(2)R(300) = 900R. (b) n = 56000/28 = 2000 mol of a diatomic gas, U = 5/2(2000)R(300) = 1.5×106 R. (c) n = 0.25 mol, U = 5/2(0.25)R(300) = 187.5R. (d) U = 3/2(1000)R(900) = 1.35×106 R. The largest is (b).
