An ideal gas undergoing adiabatic change has the following pressure-temperature relationship

1. P¹⁻ᵞ = constant
2. Pᵀᵞ⁻¹ = constant
3. Pᵀ¹⁻ᵞ = constant
4. Pᵀᵞ = constant

Correct answer: Pᵀᵞ⁻¹ = constant

Solution

For an adiabatic process, the relationship between pressure and temperature is derived using the adiabatic condition PV^γ = constant and the ideal gas law. This leads to P*T^(γ-1) = constant.
