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

Text Solution

Verified by Experts

The correct Answer is:
C
`2g H_2 rArr` mole gas at 200K
`28g N_2 rArr 1` mole gas at 400K
PV = nRT
`rArr P prop nT.`
