The hole in a rubber stopper is used to allow for the insertion of glass tubing or a thermometer into a container without disrupting the seal created by the stopper. This allows for measurements or additions to be made to the container while maintaining a closed system.
The reaction between magnesium and hydrochloric acid produces hydrogen gas, which builds up pressure inside the closed glass tube. If the pressure exceeds the strength of the rubber stopper, it will burst off to release the built-up pressure and prevent the glass tube from breaking due to the increased pressure.
To avoid loss of substances.
As the radius of rotation decreases, the number of revolutions of a rubber stopper increases. This is due to the conservation of angular momentum - with a smaller radius, the rotational speed must increase to maintain the same angular momentum.
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
When pushing a needle through the rubber stopper of a vial, there is a potential risk of contamination if proper aseptic technique is not followed. It is important to ensure the needle is sterile, the stopper is disinfected before puncturing, and proper hand hygiene is maintained to prevent introducing microorganisms into the vial. Additionally, care should be taken to avoid needle stick injuries.

The volume of a rubber stopper can vary depending on its size and shape. To find the volume of a rubber stopper, you can use the formula for the volume of a cylinder or sphere, depending on the shape of the stopper. Measure the dimensions of the stopper and plug them into the appropriate formula to calculate the volume.
No, rubber is denser than water, so a rubber stopper would sink in water.
No, the density of a rubber stopper is less than the density of water. Rubber has a lower density compared to water, so a rubber stopper would float on water.
The volume of the stopper can be calculated by subtracting the initial volume of the water from the final volume. In this case, the volume of the rubber stopper would be 30.9 ml - 25 ml = 5.9 ml. Now, divide the mass of the rubber stopper (8.46 g) by its volume (5.9 ml) to find its density. Density = Mass/Volume, so the density of the rubber stopper would be 8.46g / 5.9ml = 1.43 g/ml.
This is very variable and depends on: - type of rubber - temperature - pressure on the stopper - the liquid in contact - other conditions of use

remove the pedal arm pin so that you can freely move the pedal and have an access to the rubber stopper slots.
KCIO3-MNO2 cannot comes in contact with the rubber stopper otherwise, or a severe explosion may result.
