Otto von Guericke contributed to the particle theory by conducting the famous Magdeburg hemispheres experiment which demonstrated the concept of a vacuum and the existence of air pressure. His work helped in understanding the nature of particles and their behavior in a vacuum.

How did Otto Von Guricke demonstrate atmospheric pressure?

Otto von Guericke used a water pump that he modified in order to pump the air out of two brass hemispheres that were joined together as a sphere. Then, in a famous demonstration, he used two teams of horses to try and pull the two hemispheres apart but they could not. He explained it was the pressure of the atmosphere that was holding the two halves together and that a vacuum could exist on earth.


What are the factors that contribute to the efficiency of the Otto cycle?

The efficiency of the Otto cycle is influenced by factors such as compression ratio, combustion process, and heat transfer. These factors impact the amount of work produced by the engine relative to the energy input.


Who built the first machine that produced charges by rubbing a rotating ball?

The first machine that produced charges by rubbing a rotating ball was built by Otto von Guericke in the 17th century. This machine, known as the "sulfur globe," used friction to generate static electricity by rubbing a rotating ball made of sulfur against a cloth.


What is the formula to calculate the thermal efficiency of an Otto cycle engine?

The formula to calculate the thermal efficiency of an Otto cycle engine is: Thermal Efficiency 1 - (1 / compression ratio)


Who was the German scientist who devised an internal combustion engine fueled by gasoline in 1886?

Otto (which started the term "Otto Motor" in Germany) In 1876 Nikolaus Otto built a four-stroke or "Otto cycle" internal combustion engine. Gottlieb Daimler & Wilhelm Maybach who had worked with Otto on his engine, parted company and in 1885 released their own much advanced version. In 1886 Karl Benz patented his "motorwagen" and is generally credited as being the father of the automobile.
