Question

A bolloon blown up has a volume of 300 mL at `27%` C. The balloon is distended to `(5)/(6)` of its maximum stretching capacity. The maximum temperature above which it will burst is
A. `77^@C`
B. `67^@C`
C. `57^@C`
D. `87^@C`

Answer 1

Correct Answer - D
Maximum capacity `=300xx(6)/(5)=360mL`
If volume is more that 360, it will burst.
`(V_(1))/(T_(1))=(V_(2))(T_(2))`
`(300)/(300)=(360)/(T_(2))`
`T_(2)=360K=360-273=87^@C`
