Answer:

The change in internal energy (∆U) of the balloon is -465.7 units. The negative sign indicates that the internal energy of the balloon has decreased.

Step-by-step explanation:

To find the change in internal energy of the balloon, we can use the First Law of Thermodynamics, which states:

Change in internal energy (∆U) = Heat added (Q) - Work done by the system (W)

Given:

Heat added (Q) = 97.3 units

Work done by the system (W) = 563 units

Now, let's plug in the values:

∆U = 97.3 - 563

∆U = -465.7

Therefore, the change in internal energy (∆U) of the balloon is -465.7 units. The negative sign indicates that the internal energy of the balloon has decreased.
