To study the electrical conductivity of gases, we will strengthen two metal plates parallel to each other, connect one to the rod, and the other to the body of the electrometer, and give them opposite charges. The electrometer does not discharge, therefore, no current flows through the air between the plates. We introduce a flame into the space between the plates – the electrometer is quickly discharged. This experience shows that the gas becomes a conductor under the influence of a flame.
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.
