Now consider that the above sample of 12 g of Helium, at its final temperature ` 227^(@)C,` C, is contained in a container X. Another container Y has also Helium at the same temperature and pressure as in container X but container Y has three times the volume of container X. Assuming that Helium in both containers behaves as an ideal gas, answer these questions.
Internal energy of the gas in container Y will be -

Options

A. unrelated to that for container X
B. three times that for container X
C. one third of its value for container X
D. the same as that for container X

Answer
