Q. Assertion : Glass panes fixed to windows or doors of old buildings are slightly thicker at the bottom than at the top.
Reason : Glass is a pseudo solid or supercooled liquid.

The Solid State

Solution:

Glass panes fixed to windows or doors of old buildings are found to become thicker at the bottom because the glass is supercooled liquid and it flows down very slowly and makes the bottom portion thicker. Hence, both assertion and reason are correct.
