Question

A balloon blown up with 1 mole of gas has a volume of 480 ml at 14'c. At this stage, the balloon is filled to 7/8th of its maximum capacity. Suggest (a) will the balloon burst at 30°c (b) the minimum temperature at which it will burst

Answer 1

Maximum capacity or volume of balloon <br>

<br> Also

mole <br> (a) The ballon will burst at the temperature say

when volume becomes

<br>

<br>

<br>

<br> Thus ballon will not burst at

<br> (b) The minimum temperature at which ballon dursts is

<br> (c ) Pressure of gas at

having 1 mole and <br>

<br>

<br>

<br> (d) Since

increases with temperature rise from

to

at which ballon bursts and therefore pressure remains constant Thus pressure of gas in ballon when it bursts in
