Why does door shuts firmly during rainy season?
I observed our front door nowadays shuts firmly. Otherwise , for small breeze also, it is flung open and it would be a open scene.
I know it always happens only in rainy season. During other season, we must latch it . But during rainy season , no need to latch it ! ( only during day time ) .
Since our front door is made of wood , I know this particular phenomena is called " Imbibition ".
What is Imbibition?
Imbibition is the absorption of water by hydrophilic substances. Like our front door which is made of wood.
This happens when dry seeds germinate.
During imbibition, a substance absorbs water or water content and swells . Because of this swelling of our front door , it shuts firmly opposite to its case , and much force is required to open it . But during summer, there is less water content in atmosphere , hence it contracts.( comes to its original position ) . It happens when water content or moisture becomes less.
