When a numerical value is required, we use = 5/3, the value for a monatomic ideal gas. The adiabatic exponent = 5 is taken for a monatomic 3 gas, such as ionized hydrogen in the solar corona. In this temperature region, such a gas becomes monatomic and again behaves like a perfect gas. When you shine white light, which is a continuous spectrum of colours, into a monatomic gas, you get back precise line spectra, and only quantum mechanics can explain this phenomenon.
