Because... if it's tightly sealed - during cooling the volume of the solvent will decrease - making the pressure inside lower than outside he flask. This could be enough for the glass to shatter - spilling the contents.
density
its not a substance its a state of matter which is the solid the solid's particles are packed tightly together glad 2 help !! :)
They are tightly packed and vibrate.
creates pressure
like this ::::::::::::: ::::::::::::: ::::::::::::: though a little closer. It depends on the metal, but atoms in a pure solid are tightly-packed into a crystalline structure. The shape of the crystal is dependent upon the atom.

It is not recommended to store sodium hydroxide in an Erlenmeyer flask because the strong base can react with the glass, causing potential damage or breakage of the flask. It is better to store sodium hydroxide in a container made of a material that is compatible with strong bases, such as high-density polyethylene or glass specifically designed for chemical storage.
When cold water is poured on a tightly corked tin can containing steam, the rapid cooling of the steam creates a pressure difference that causes the can to crush. The steam condenses into water, leaving a vacuum inside the can. The external atmospheric pressure then crushes the can due to the lack of pressure inside.
Heterochromatic regions of the genome are tightly packed and less active, containing genes that are usually turned off. Euchromatic regions are loosely packed and more active, containing genes that are typically turned on.
Air pressure from outside and vacuum effect from inside.
Slow because Quartz is a very stable mineral at the Earth's surface and is very tightly bound giving it very unusual and useful properties.
more tightly, most tightly
To make a bleach solution effectively and safely, mix 1/3 cup of bleach with 1 gallon of water. Use gloves and work in a well-ventilated area. Do not mix bleach with other cleaning products. Store the solution in a labeled, tightly sealed container.

Transfer approx. 600 mL of demineralized water in a 1 L volumetric flask; add very slowly 324,24 mL of 98 % sulfuric acid. Wait to cool at 20 0C in a thermostat; add slowly water up to the mark. Avoid splashes ! Stir the content of the flask, transfer the solution in a tightly stoppered glass or polythene bottle; put a label on the bottle containing the name of the solution, concentration, date, operator. For accuracy is necessary to titrate the solution with sodium hydroxide.
No, oxygen cannot be liberated from all oxygen-containing compounds. Some compounds contain oxygen in a very stable form, such as in water (H2O), where the oxygen is tightly bound to hydrogen. Releasing oxygen from these compounds would require significant energy input.
Tightly is an adverb.
