Why did the water rush into the erlenmeyer flask when it was submerged in the cold water?
1. When the flask was placed into the cold water, the colder air molecules in the flask move slower, putting out less pressure. With the decrease in air pressure inside the flask, the now greater pressure outside pushes water into the flask until the pressure inside equals the pressure outside.

Why is a thermos flask good at keeping drinks cold as well as hot?
Because it has good insulation so it prevents boss loss and gain of heat from the surrounding ---- Well that's true, but more interestingly, it has a glass chamber inside which is smaller than the outer casing. The air between the glass chamber and the outer casing has had almost all of the air removed, and is therefore a vacuum. This makes the heat unable to escape between the inner chamber and the outer casing, keeping the liquid hot. It also stops heat from outside being able to get into the liquid stored in the glass chamber, therefore keeping it cold. Most of the heat from the flask is lost from the lid, since the liquid has to come out of somewhere.
