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

A vessel containing 1 mole of `O_(2)` gas (molar mass 32) at tempeature T. The pressure of the gas is P.An identical vessel containing onle mole of He gas (molar mass 4) at temperature 2 T has a pressure of [2013]

A

`P//8`

B

P

C

P

D

` 8P`

Text Solution

Verified by Experts

The correct Answer is:
C
Applying gas equation,`pV=nRT`
We can write,`p_(1)V=n_(1)RT_(1)`
and `P_(2)V=n_(2)RT_(2)`
`rArr p_(2)/p_(1)=n_(2)/nm_(1)xxT_(2)/T_(1)`
`=1/1xx(2T)/(T)=2`
`rArr P_(2)=2P`
