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

A

`P//8`

B

P

C

2P

D

8P

Text Solution

Verified by Experts

The correct Answer is:
C
As V= constant
`P prop nT implies (P_2)/(P_1)=(n_2T_2)/(n_1T_1)`
`implies (P_(He))/(P)=1/1 xx (2T)/(T) implies P_(He)=2P`
