Question

Choose the correct option for free expansion of an ideal gas under adiabatic condition from the following :

• A. $q = 0, \, \Delta T \neq 0, \, w = 0$
• B. $q = 0, \, \Delta T = 0, \, w = 0$
• C. $q \neq 0, \, \Delta T = 0, \, w = 0$
• D. $q = 0, \, \Delta T<0, \, w \neq 0$

Answer 1

Answer: (B)

$q = 0, \, \Delta T = 0, \, w = 0$

Answer 2

During free expansion of an ideal gas under adiabatic conditions, there is no transfer of heat, no work is done, and the temperature remains constant.
