Question
A vessel contains 1 mole of O2 gas (molar mass 32) at a temperature T. The pressure of the gas is p. An identical vessel containing one moles of the gas (molar mass 4) at a temperature 2T has pressure of
Options
A.p/8
B.p
C.2p
D.8p
Solution
pV = nRT or P = 
or P ∝ T
if V and n are same. Threfore, if T is doubled, pressure also becomes two times i.e., 2 p.
or P ∝ T if V and n are same. Threfore, if T is doubled, pressure also becomes two times i.e., 2 p.
