A vessel containing 1 mole of O(2) gas (...

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

A

P/8

B

2P

C

P

D

8P

Text Solution

Verified by Experts

The correct Answer is:
B
PV=nRT
`thereforeP_(1)V=n_(1)RT_(1)` and `P_(2)V=n_(2)RT_(2)`.
`therefore(P_(2))/(P_(1))=(n_(2))/(n_(1)).(T_(2))/(T_(1))rArrP_(2)=Pxx1xx2=2P`
`therefore` Correct choice is (b).
