1 mole of an ideal gas is contained in a cubical volume 
at 300 K (see figure). One face of the cube ( 
) is made up of a material which totally absorbs any gas molecule incident on it. At any given time.
A
the pressure on 
would be zero
would be zero B
the pressure on all the faces will be equal
C
the pressure of 
would be double the pressure on 
would be double the pressure on D
the pressure on 
would be half that on 
would be half that on
Text Solution
Verified by ExpertsThe correct answer is:
D
In an ideal gas, when a molecule collides elastically with a wall, the momentum or pressure transferred to each molecule will be twice the magnitude of its normal momentum. As face 
absorbs the molecule incident on it, so for the face 
, it transfers only half of that on other faces.
