A system of four moles of an ideal gas increases its internal energy by 2,992 J as it increases in temperature from 300 K to 360 K. There are no changes in bond energy. Which of the following statements is true? Explain using the appropriate model(s).
(a) This gas is monatomic.
(b) This gas is diatomic, with its vibrational modes frozen out.
(c) This gas is diatomic, with its vibrational modes unfrozen.
(d) Not enough information given; you need to know how much work was done on the gas.
(e) Not enough information given; you need to know how much heat was transferred to the gas.
(f) Both (d) and (e)
