🔍 Key Concepts

• Adiabatic process definition in thermodynamics • What condition must be true for no heat transfer to occur • How gas turbines compress air in relation to time and heat exchange

💭 Think About

• Think about which choice best matches the condition where a gas is compressed without gaining or losing heat to its surroundings • Ask yourself: in which situation does the gas have the least time to exchange heat with the environment? • Consider whether cooling between stages or over time would still be considered adiabatic

✅ Before You Answer

• Verify which option is directly related to heat transfer being negligible or zero • Check whether interstage cooling or heat transfer can exist in a truly adiabatic process • Eliminate any choice that describes a non-ideal or clearly non-adiabatic situation (like deliberate cooling)
