Question

A toy balloon can occupy 500 ml at 27°C. The maximum stretching capacity of the balloon is three times of the volume at 27°C. At what temperature above which the balloon will burst, if pressure of the balloon does not change

Prashant Kotian · Accepted Answer

Correct answer: C. Under constant pressure, Charles's law applies: V1 / T1 = V2 / T2. Given: V1 = 500 ml, T1 = 27 + 273 = 300 K. The maximum volume V2 before bursting is 3 * 500 = 1500 ml. T2 = (V2 * T1) / V1 = (1500 * 300) / 500 = 900 K. Converting to Celsius: 900 - 273 = 627°C. The closest option is 625°C.
