Adiabatic Process
An adiabatic process is a thermodynamic process in which no transfer of heat takes place between the system and its surroundings. In other words, the system is thermally isolated and there is no exchange of heat energy.
Free Expansion of an Ideal Gas
Free expansion is a process in which an ideal gas expands into a vacuum without any external work being done on the system. This means that the gas expands freely and no work is done by or on the gas.
Options for Free Expansion of an Ideal Gas under Adiabatic Conditions
Let's analyze the given options to determine the correct one:
a) q = 0, T ≠ 0, w ≠ 0
This option states that there is no transfer of heat (q = 0) but the temperature (T) and work (w) are not zero. This contradicts the definition of an adiabatic process where no heat transfer occurs. Therefore, this option is incorrect.
b) q = 0, T = 0, w = 0
This option correctly states that there is no transfer of heat (q = 0) and both the temperature (T) and work (w) are zero. In a free expansion process, the gas expands into a vacuum and does not exchange heat with the surroundings. As a result, the temperature remains constant and no work is done. Hence, this option is the correct answer.
c) q = 0, T ≠ 0, w = 0
This option incorrectly states that the temperature (T) is not zero even though there is no transfer of heat (q = 0). This violates the definition of an adiabatic process. Therefore, this option is incorrect.
d) q ≠ 0, T = 0, w = 0
This option states that there is a transfer of heat (q ≠ 0) but both the temperature (T) and work (w) are zero. This contradicts the definition of an adiabatic process where no heat transfer occurs. Therefore, this option is incorrect.
Conclusion
The correct option for the free expansion of an ideal gas under adiabatic conditions is option 'B' because it correctly states that there is no transfer of heat (q = 0), the temperature is zero (T = 0), and no work is done (w = 0).
