One of the ways to measure the speed of molecules was proposed by Stern. In this experiment, silver atoms, evaporating from the wire, passed through the slit of the first cylinder and settled on the inner surface of the second cylinder. In this case, both cylinders rotated at a constant speed, therefore, while the silver particle was moving between the cylinders, the cylinders were displaced by a certain distance. The velocity of the molecules can be estimated from the displacement of the silver strip.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
