Approved Tutor Answer11 Months agoIn an adiabatic compression process, the relationship between pressure (P) and volume (V) is governed by the equation PV^γ = constant, where γ (gamma) is the heat capacity ratio. This means that as the volume decreases during compression, the pressure increases, leading to a change in the product PV.
Understanding the Options
- A. Increases - This is not correct because the product PV does not simply increase during compression.
- B. Decreases - This is also incorrect; PV does not decrease in adiabatic processes.
- C. Remains constant - This is true for isothermal processes, not adiabatic ones.
- D. Depends on γ - This is the correct answer, as the value of PV changes based on the specific heat ratio γ.
Therefore, the correct answer is D. Depends on γ.
