Volum at the beginning: 
Volum at the end:
α for helium =
As the result you get:
Final volume of the balloon is 22,9264 liters.
(Only if it doesn't explode during being heated ;) just a joke)

Explanation:
Given that,
Number of turns in the coil, N = 52
Original are of the coil,
It is stretched to have no area in 0.100 s, t = 0.1 s
The magnetic field strength, B = 1.2 T
To find,
The magnitude and the direction of average induced emf.
Solution,
The Faraday law gives the magnitude and the direction of induced EMF in the coil. Its formula is given by :
E = 171.6 volts
The direction of induced emf is given by Lenz law. It opposes the direction due to which it is produced. It is in counterclockwise direction.
