The amount of heat transferred to the thermodynamic system is 2000 J.

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.
