Volum at the beginning: \(V_{1}=10\)
Volum at the end:
\(V_{2}=V_{1}*(1+ \alpha* (t_{2}-t_{1}))\)
\(t_{2}-t_{1}=50-10=40\)
α for helium = \(0,003658\frac{1}{C}\)
As the result you get:
\(V_{2}=20*(1+0,003658*40)=22,9264 l\)
Final volume of the balloon is 22,9264 liters.
(Only if it doesn't explode during being heated ;) just a joke)
