cork is a stopper to close wine bottles
Bottle stoppers can generally be purchased at a range of stores. These include supermarkets, corner shops, and the slightly higher-end of wine stores and off licenses.
A corked bottle of white wine typically lasts about 3 to 5 days once opened if stored in the refrigerator. If the bottle remains unopened, it can last for several years, depending on the type and quality of the wine. However, once exposed to air, the wine begins to oxidize, which affects its flavor and quality over time. To maximize freshness, reseal the bottle with its cork or a wine stopper.
A stopper for a bottle is commonly referred to as a cork. Corks are typically made from the bark of cork oak trees and are used to seal wine and other beverage bottles. Other types of stoppers can include screw caps or plastic stoppers, depending on the bottle's design and intended use.
The purpose of a wine stopper is to cork the remaining wine in a bottle before putting it on a rake or into the refrigerator since using the original cork is sometimes difficult to put back into the bottle.

With a few exceptions (notably melting ice) objects expand when heated. If you run hot water on a bottle neck, the heat is applied directly to the bottle and only indirectly to the stopper inside the bottle, so the bottle heats first, and thereby expands sooner than the stopper does. An expanded bottle will exert less pressure on the stopper.
Increasing the pressure on the stopper in a bottle of water will compress the air inside, which in turn increases the pressure. This will cause the pressure inside the bottle to rise. Conversely, releasing the stopper will decrease the pressure inside the bottle as the air expands.
