A balloon filled with helium gas having pressure 2 atm was kept at room temperature (of `27^(@)`C). What will be the resulting temperature if it bursts? (Assume that change occurs reversibly)
`{:((1),-60^(@)C,(2),-45.65^(@)C),((3),-30.15^(@)C,(4),-10.5^(@)C):}`

Explanation

To solve the problem, we need to determine the resulting temperature of helium gas in a balloon when it bursts, under the assumption that the process is adiabatic (no heat exchange with the surroundings).

### Step-by-Step Solution:

1. **Identify Initial Conditions:**
- Initial Pressure, \( P_1 = 2 \, \text{atm} \)
- Initial Temperature, \( T_1 = 27^\circ C = 300 \, \text{K} \) (Convert Celsius to Kelvin by adding 273)
