During an adiabatic expansion, the increase in volume is associated with which of the following possibilities w.r.t.w\mathrm{.r}\mathrm{.t}\mathrm{.} pressure and temperature 
View answer and explanation
Correct option: B
Pressure - Decrease ; Temperature - Decrease
Option B (Pressure - Decrease ; Temperature - Decrease) is correct because in an adiabatic expansion, the gas does work, reducing its internal energy and thus both temperature and pressure decrease.
