A vessel contains 1 mole of `O_2` gas (relative molar mass 32) at a temperature T. The pressure of the gas is P. An identical vessel containing one mole of He gas (relative molar mass 4) at temperature 2T has a pressure of

A

P/B

B

P

C

2P

D

BP

Text Solution

Verified by Experts

The correct Answer is:
C
`PV = nRT" or " P = (nRT)/V" or "P prop T`
If C and n are the same. Therefore, if T is doubled, pressure also becomes two times, i.e., 2 P.
