Which of the following relations does not give the equation of an adiabatic process, where terms have their usual meaning?

1. P T^(γ-1) = constant
2. P^(1-γ) T = constant
3. P/V = constant
4. TV^(γ-1) = constant

Correct answer: P/V = constant

Solution

For an adiabatic process, the relations involve pressure (P), volume (V), and temperature (T) in specific forms. The relation P/V = constant is incorrect as it does not represent an adiabatic condition.
