Question

Q. Two inflated balloons 1 and 2 (thin skin) having volume 600 ml and 1500 ml at 300 K are taken as shown in diagram. If maximum volume of inner and outer balloons are 800 ml and 1800 ml respectively then find the balloon which will burst first on gradual heating....
a. inner balloon b.outer balloon c.both simultaneously d. unpredictable

Answer 1

Answer:

Explanation:

Given  

Suppose inner balloon burst first

We get 600 / 300 = 800 / T2

T2 = 800 x 300 / 600

T2 = 400 K

Suppose outer balloon burst first

We get 1500 / 300 = 1800 / T2

T2 = 1800 x 300 / 1500

T2 = 360 K  

So outer balloon will burst first

Answer 2

Answer:

b.outer balloon  will burst first.

Explanation:

If we take for the inner balloon so, it has volume of 600 ml and temperature of 300k.

So, on applying Charles law we know that volume at constant pressure is directly proportional to its temperature. So, we will get 600/300 = 800/T2.

T2 = 800 x 300 / 600

So, the value of T2 = 400 K.

Now, for the outer balloon again applying Charles law we will get that volume is directly proportional to its temperature at constant pressure.

So, we will get that 1500/300 = 1800 / T2.

T2 = 1800 x 300 / 1500.

On solving we will get T2 = 360 K.

Since, the  outer balloon is having the break point temperature to be less so, the outer balloon will burst first.
