A balloon has a volume 400 ml at 0 ° C . The balloon is distended to 4/5th of its maximum stretching capacity. (i) Will burst if it is brought into a room at 40 ° C ? (ii) What is the maximum temperature above which it will burst?

Options

  1. ABalloon will not burst at 40 ° C, balloon will burst above 40 ° C
  2. BBalloon will burst at 40 ° C, balloon will not burst above 68.25 ° C
  3. CBalloon will not burst at 40 ° C, balloon will burst above 68.25 ° C
  4. DNone of these

Correct answer

C. Balloon will not burst at 40 ° C, balloon will burst above 68.25 ° C

Step-by-step solution

(i) Maximum stretching capacity = 400 × 5 4 = 500 ml V 1 T 1 = V 2 T 2 or 400 273 = V 2 313 V 2 = 458.61 ml If the volume becomes more than 500 ml it will burst. The volume is below 500 ml, hence it will not burst at 40 ° C . (ii) V 1 T 1 = V 2 T 2 or 400 273 = 500 T 2 T 2 = 341.25 K = 68.25 ° C The temperature at which the volume becomes 500 ml the balloon will burst. So balloon burst above 68.26 ° C .
