Question:
A gas undergoes an adiabatic process. During this process:
A gas undergoes an adiabatic process. During this process:
Show Hint
Adiabatic processes often occur so quickly that the system does not have time to exchange heat with its surroundings.
Updated On: May 27, 2026
- No heat is exchanged with the surroundings
- The temperature of the gas remains constant
- The pressure of the gas remains constant
- The volume of the gas remains constant
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept: Thermodynamic processes are classified based on the constraints on heat exchange, temperature, pressure, or volume. An adiabatic process is specifically defined by the lack of thermal energy transfer.
Step 1: Define the adiabatic condition. In thermodynamics, a process is adiabatic if the heat exchanged with the surroundings, $dQ$, is equal to zero.
Step 2: Evaluate the options based on the definition. (A) True: Adiabatic implies $dQ = 0$.
(B) False: This describes an isothermal process.
(C) False: This describes an isobaric process.
(D) False: This describes an isochoric (or isometric) process.
