The modern rubber stopper was developed in the 19th century, with significant contributions from Charles Goodyear, who is known for his work on vulcanization of rubber in 1839. This process made rubber more durable and elastic, paving the way for its use in various applications, including stoppers. While Goodyear didn't invent the rubber stopper itself, his innovations in rubber technology were crucial for its development.

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.
i don't know... That's why I'm asking you. soo.. Does a rubber stopper float in water?
Vulcanized rubber was invented in 1841 by Charles Goodyear, and the new substance was immediately put into use for many purposes. In 1842 a man called Brockedon reported to the British Chemistry Association that he had invented a stopper for use in chemistry which was a cotton cord bound with flax and coated with rubber. Solid hard rubber stoppers were used to close beer and liquor bottles in Britain by the 1880s, using the internal screw stopper patented by Henry Barrett in 1872. Such stoppers were extremely popular in both Britain and America between 1880 and 1920 or so.
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.
