An open vessel containing air is heated from 300 K TO 400 k . THE FRACTION OF AIR ORIGINALLY PRESENT WHICH GOES OUT OF IT IS :
As learnt in
Ideal Gas Law -
- wherein
P - Pressure
V - Volume
n - No. of Moles
R - Gas Constant
T - Temperature
PV = nRT , T1 = 300k , T2 = 400k
Since, it is an open vessel, pressure is constant and there is no change in the volume of vessel.
P1 = P2 and V1 = V2
Therefore, fraction of air that goes out
Option 1)
This option is incorrect
Option 2)
This option is correct
Option 3)
This option is incorrect
Option 4)
This option is incorrect
