Question

A certain amount of gas filled in balloon of volume 400 mL at a pressure of 0.5 bar. Calculate the pressure of gas when the the balloon is expanded to 600 mL at 27 °C.

PLZ I need Correct answer with Explanation
​

Answer 1

Answer:

Maximum capacity of balloon =

7

8

×480=548.57mL

Let T be the temperature at which the volume of balloon becomes 548.57mL and the balloon will burst.

Given:-

V

1

=480mL

V

2

=548.57mL

T

1

=5℃=(273+5)K=278K

T

2

=T(say)=?

Now, using Charle's Law,

V∝T

⇒

V

2

V

1

=

T

2

T

1

⇒

548.57

480

=

T

278

⇒T=

480

278×548.57

⇒T=317.71K=44.71℃

Hence the balloon will burst at 44.71℃.

(a) The balloon will not burst at 30℃.

(b) The minimum temperature above which it will burst is 44.71℃.
