| **The amount of heat transferred to the thermodynamic system is 2000 J. External forces accomplished the work of 1000 J. In this case, the internal energy?**

To find the change in the internal energy of a given thermodynamic system, we will use the formula: U = Q + A.

Values of variables: Q – transferred heat (Q = 2000 J> 0, since the system received heat); A – work (A = 1000 J> 0, since external forces worked on the system).

Calculation: U = Q + A = 2000 + 1000 = 3 * 10 ^ 3 J = 3 kJ.

Answer: The internal energy of a given thermodynamic system has increased by 3 kJ.
