A balloon filled with helium (

32^\circ C

and 1.7 atm) bursts. Immediately afterwards; the expansion of helium can be considered as

View answer and explanation

Correct option: B

irreversible adiabatic

Option A (its magnitude changes but the direction remains same) is correct because the angular momentum increases as the cylinder rolls down, but the direction stays constant.
