Question

In winter, you notice condensation water at the edges of an otherwise dry window. What is the main cause of this?

a) Poor Ventilation
b) Excessive Insulation
c) Low Indoor Humidity
d) Inadequate Sealing

Answer 1

The main cause of condensation water forming at the edges of a dry window in winter is low indoor humidity (c).

Step-by-step explanation:

The main cause of condensation water forming at the edges of a dry window in winter is low indoor humidity (c). Condensation occurs when warm, moist air inside the room comes in contact with the cold pane of glass. As the air near the window cools down, it cannot hold as much moisture, causing the excess moisture to condense into water droplets on the window surface.
