From Wikipedia:
A bung is truncated cylindrical or conical closure to seal a container, such as a bottle, tube or barrel. Unlike a lid which encloses a container from the outside without displacing the inner volume a bung is partially inserted inside the container to act as a seal. The lids for safety overpacks for 55 gallon drums sometimes may have a bung built in for access of the contents of the container. These may be referred to as fuel bungs.
A rubber stopper is sometimes called a rubber bung, and a cork stopper is called a cork. Sometimes bung stoppers used for wine bottles are referred to as "corks", even though made from another material.
ACID BURRET is a Laboratory Equipment that has a Stopclock at its Stopper.
i don't know... That's why I'm asking you. soo.. Does a rubber stopper float in water?
Since the difference in volume corresponds to the volume of the stopper, the volume of the stopper=30.9-25=5.9ml Thus density of the rubber stopper=mass/vol=(8.46/5.9)g/ml
KCIO3-MNO2 cannot comes in contact with the rubber stopper otherwise, or a severe explosion may result.
yes

The main reason for a rubber stopper is to stop gas or liquid from coming out of the container. Rubber stoppers can also prevent contamination of samples by keeping the laboratory glassware safe.
A beaker cover is called a rubber stopper or metal stopper(depends on what the stopper is made of).
This is very variable and depends on: - type of rubber - temperature - pressure on the stopper - the liquid in contact - other conditions of use

You can buy an rubber stopper at widget-co.com. They are not that expansive ethier
Rubbers stoppers are used in laboratory for: - to close bottles - to close tubes - to make a link between tubes or other laboratory objects - to make link with perforated stopper
It creates a seal stopping flow of air
rubber stopper burst up because it has strong afinity with hydrogen
A rubber bung (also called rubber stopper) is used in the laboratories for test tubes, flasks (made of glass usually). Bungs also used by winery industry for the wine bottles. A bung must fill well as a stopper. The bungs are of many sizes. Rubber bung can have one or more hole(s) for plugging in tube depending on the specification of the procedures. In chemical laboratory, to prevent the liquid chemical leaks or escape the container, we need the rubber bung that fit tightly to the container's open, therefore, the dimension of the rubber bung is concerned. These are some of the sizes that are commonly seen in chemical laboratory
Because they are not expensive, can assure a convenable sealing, are flexible, resist a long time, many reagents doesn't attack rubber, can support temperature in a wide range, the contaminatiom from the rubber is minimal, etc. Of course rubber stoppers are not recommended for all experiments.
