In a closed flask of 10 l, 4.0 g He is heated from 300 to 900 K. Which statement is not correct?
Options:
Answer:
D
Solution:
The flask is closed and rigid, so n and V are fixed; heating 300 900 K raises P = nRT/V, raises molecular speeds (more collisions), and raises average KE = 3/2kT. He cannot gain or lose moles in a closed flask — it is monatomic and does not dissociate. Statement (d) is incorrect. Confirms Ans (d).
