Solution:
1. Given:
* Internal energy of the system:U = 800 \, \text{J}
* No heat transfer:Q = 0
* No work done:W = 0
2. Use the first law of thermodynamics:
*\Delta U = Q - W
3. Substitute the given values:
* Since bothQ = 0 W = 0
\Delta U = 0 - 0
4. Simplify:
*\Delta U = 0 \, \text{J}
Hence, the change in internal energy is:
*\Delta U = 0 \, \text{J}
