As we learned

 

Nature of liquid and vapour pressure -

Liquids which are more volatile exerts more vapour pressure.

- wherein

More volatile liquids are those when intermolecular forces are weak.

 

 Vapour pressure of liquid only depends on nature of liquid and temperature. It does not depends volume, shape ro size of container.


Option 1)

More than what would be if the glass plate were removed

Option 2)

Same as what would be if the glass plate were removed

Option 3)

Less than what would be if the glass plate were removed

Option 4)
