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.

How does hot water becomes cold in a vacuum flask?
Its because there are contact points between the inner part of the flask and the outer part, which allows some thermal conductivity to occur.
Why bromine solution added gradually?
Add the bromine solution slowly and with constant shaking to ensure thorough mixing; stand the flask in cold water
What is a iron ring used for in chemistry?
It's used to hold a flask in place while subjecting it to heat or cold.
What gets cold first hot or cold water?
Isn't cold water already cold? I would say cold water gets cold first. I've heard that hot water freezes faster than cold water.
How can you keep the inside of your pewter flask from rusting or corroding from the inside out?
Pewter corrodes when it is placed in a humid environment that allows a film to develop over the metal. Under the film, the pewter will begin to corrode. My suggestion would be to rinse the flask with cold water, and allow it to dry completely before resealing the lid. If you live in an environment where you have humid, hot summers, I might even place the flask in the refrigerator as it drys. Try using some sort of rack that allows the flask to stay upside down, ensuring that all water can escape (gravity) and air can freely circulate (keeps humidity low). Never add anything other than alcohol, like a mixed drink or mixer, as these liquids are harder to clean and dry, and can allow films to develop if the flask if full for long period of time. Hope this helps!
Is a thermos flask also good for keeping water cold for several hours?
Yes. The thermos flask can reduce the amount of heat travelling from the surroundings to the cold water
Why can cold water in an uncapped vacuum flask still stay cold?
It will certainly not stay cold as long as if it were capped.
What happens when a hot chocolate is partially submerged in cold water?
nothing
What happens to lettuce if it is submerged in ice cold water?
it gets wet
Why would the water be warm on a cold day?
maybe the waters in a flask or has been next to radiator or maybe it came out of a cold tap

When water is heated why would a submerged object rise faster?
Since you asked, I don't think it would.I think a submerged object would rise slower in hot water than in cold. The densityof the hot water is less than the density of cold water. So whatever volume of fluidthe submerged object displaces has less weight, and the buoyant force on thesubmerged object is less than it would be in cold water.That's my story, and I'm sticking to it.Another answer:I agree. What makes you think an object will rise faster?
What happens if a cold substance kept in thermos flask?
It heats up and the water keeps warm for a certain amount of time
What are the names and uses of porcelain or glassware laboratory equipment?
There are 34 different glasses in the laboratory.

Why did the ink rise up when the flask is immersed into a hot water?
When the flask is immersed into hot water, the ink molecules gain thermal energy causing them to move more rapidly. This increased movement disrupts the intermolecular forces holding the ink together, making it less dense and causing it to rise up in the flask.
Why bromine solution added gradually?
Add the bromine solution slowly and with constant shaking to ensure thorough mixing; stand the flask in cold water
Water vapor and air inside an aluminum container are heated to a high temperature The container is then submerged in ice cold water Why does the aluminum container collapse?
When water is heated, water vapor forces the air out. When submerged in cold water, the water vapor condenses instantly, leaving a partial vacuum in the can, Atmospheric pressure (14.7 psi) acting on the outside of the can crushes the can before air can rush through the opening in the can to balance the pressure. Fun science experiment, just be careful not to get burned.
