Consider two sealed jars of equal volume. One contains 2 g of hydrogen

1.	Consider two sealed jars of equal volume. One contains 2 g of hydrogen at 200 K and the other contains 28 g of nitrogen at 400 K. The gases in the two jars will have - (A) the same pressure (B) the same average kinetic energy (C) the same number of molecules (D) the same average molecular speed
Answer» Correct Option :- (C) the same number of molecules Explanation :- 2g H₂ ⇒ 1 mole gas at 200 K 28g N₂ ⇒ 1 mole gas at 400 K PV = nRT ⇒ P ∝ nT

Answer»

Correct Option :- (C) the same number of molecules

Explanation :-

2g H₂ ⇒ 1 mole gas at 200 K

28g N₂ ⇒ 1 mole gas at 400 K

PV = nRT

⇒ P ∝ nT
