Ideal gas concept
The ideal gas is an ideal model established by people to simplify the actual gas. The ideal gas has the following two characteristics: ① The molecule itself does not occupy volume; ② No interaction force between molecules. In practical applications, the gas under conditions of not too low temperature (ie high temperature, boiling point of super-gaseous material) and not too high pressure (ie low pressure) can be regarded as ideal gas, and the higher the temperature, the lower the pressure, the closer Ideal gas.
