15. A toy balloon blown up at 5°C has a volume of480 ml. At this stage, the balloon is distended to8/7th of its maximum stretching capacity.(i) Will the balloon burst if it is brought to a roomhaving temperature 30°C? (ii) Calculate the temperature at which the balloonwill burst.

Answer:
55
Explanation:
Given A toy balloon blown up at 5°C has a volume of 480 ml. At this stage, the balloon is distended to 8/7th of its maximum stretching capacity.(i) Will the balloon burst if it is brought to a room having temperature 30°C? (ii) Calculate the temperature at which the balloon will burst.
We know that according to Charles law
V1 / T1 = V2 / T2
Initial volume = 480 ml
Final volume = 480 x 8/7
The volume at which the balloon burst will be the final volume.
Initial temperature = 14 degree Celsius = 14 + 273 = 287 K
So substituting we get
480 / 287 = 480 x 8/7 / T2
7T2 = 287 x 8
T2 = 328
T2 = 55 degree Celsius.

The balloon will not burst .
The balloon will burst when the temperature is 55 degree Celsius.
