Question

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

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

Answer 1

The correct option is C $q=0,\Delta T=0,w=0$

For an adiabatic process, heat exchange between the system and the surrounding is zero i.e, $q=0$.
For a free expansion of an ideal gas, $w=0,\Delta T=0$.
