Answer:
Yes! They can be correct
Explanation:
An isolated system is a system where its total energy and mass stay constant.
In this case, even though the volume changed, the mass remains constant (m = 1 kg), so there is no mass exchange, and we must think that the globe is completely closed.
Now, we don't know exactly what happens with energy, but I can give you an example where the total energy of the globe remains constant.
Imagine that the balloon of volume [tex]V_1[/tex] is at a certain height [tex]h_1[/tex], under some pressure, [tex]P_1[/tex]. If you lower the balloon to a height [tex]h_2[/tex], the pressure increases, and from the Boyle's law,
[tex]P_1 V_1 = P_2 V_2[/tex],
[tex]V_2 = V_1 \frac{P_1}{P_2}[/tex], where [tex]P_2 > P_1[/tex],
[tex]V_2 < V_1[/tex], just like the case you state, and there was no exchange of mass or energy related to the inner gas of the balloon, so yes, They can be correct.
