JEE PYQ: Thermodynamics Question 15
Question 15 - 2020 (03 Sep Shift 1)
A balloon filled with helium (32$°$C and 1.7 atm.) bursts. Immediately afterwards the expansion of helium can be considered as :
(1) irreversible isothermal
(2) irreversible adiabatic
(3) reversible adiabatic
(4) reversible isothermal
Show Answer
Answer: (2)
Solution
Bursting of helium balloon is irreversible and in this process $\Delta Q = 0$, so adiabatic.
