Adiabatic Process

Question

For adiabatic compression of ideal gas, which remains constant?

RankGuru · Accepted Answer

1. **Definition**: An adiabatic process is one in which there is **no heat exchange** between the system and its surroundings ($Q = 0$).
2. **Governing Equation**: For a reversible adiabatic process, $PV^\gamma = 	ext{constant}$ (where $\gamma = C_p/C_v$).
3. **Variables**: During adiabatic compression, both pressure ($P$) and temperature ($T$) increase, while volume ($V$) decreases. Therefore, $PV$ and $T$ are NOT constant.
4. **Entropy**: For a *reversible* adiabatic process, entropy is constant (isentropic). However, 'heat exchange being zero' is the fundamental defining characteristic of all adiabatic processes.
5. **Conclusion**: **Heat exchange** is zero by definition.
