1 mole of an ideal gas is contained in a cubical volume V, ABCDEFGH at 300 K as shown in figure. One face of the cube (EFGH) is made up of a material which totally absorbs any gas molecule incident on it. At any given time,

A

the pressure on EFGH would be zero

B

the pressur all the faces will the equal

C

the pressure pf EGGH would be double the pressure on ABCD

D

the pressure on EFGH would be half that on ABCD

Text Solution

Verified by Experts

The correct Answer is:
A
In an ideal gas, when a molecule colides elasitically with a wall, the momentum transferred to each molecule will be twice the manitude of its normal momentum. For the face EFGH, it transfere only half of that on other faces.
