Question

why do glue in the container of fevicol do not sticks in it

Answer 1

Answer:

When white glue is inside a bottle, there's not enough air inside the bottle to cause the water to evaporate to make the glue sticky. Basically, the bottle protects the glue from the air and keeps the glue runny. ... This chemical bonds things together when it reacts with water vapor in the air.

Answer 2

$\huge \fbox \purple{❧Answer}$

Glue(Fevicol) needs air to start the drying process. Since there is no air inside the container, it does not stick to it's container.

Glue on paper: As the glue connects with oxygen it becomes sticky and if left to dry in this oxygen it becomes hard and keeps multiple things together.

Glue inside the bottle: Glue doesn't stick inside the bottle because the chemicals within the glue is triggered by oxygen (what we breathe) so when the glue bottle is opened it triggers the chemicals to make it sticky. That's why if a bottle if left out with no cap the glue becomes quite hard.

Glue won't completely stick unless it's dried, and because inside the bottlee, the glue is still air locked in and not dried, it doesn't stick.

Hope it helps u! :)
