Correct Question:
Why is window's pane of heritage building taper at top and thick at bottom?
Correct Answer:
Window panes of heritage buildings are taper at top and thick at bottom due to the flow of glass with time.
- Glass is said to be a super cooled liquid or a pseudo solid.
- It has very high viscosity.
- So, in a very long duration of time, it flows down slowly.
- Due to this reason, the window pane gets thicker at the bottom and tapered at the top.
