We have disassembled the equation of the condition for ideal gas. But, there are distinctions between the ideal gas and the real one. The formula (5.2) for real gas will have some differences and amendments.
In this case we’re interested in the substance that is in a gas-plasma state. Since it is probable, that in the stars atmosphere the substance is in the state of both gas and plasma.
In the moment of birth and death of a star, the gas partially or completely transfers into plasma and back. We shall try to logically deduce the formula that considers this state as well. Why does the gas transfers into a plasma state, and plasma passes in a gas state?
