# Problem: Which of the following is true of the internal energy of the system and its surroundings following a process in which ΔEsys = +65 kJ.a. The system and the surroundings both lose 65 kJ of energy.b. The system and the surroundings both gain 65 kJ of energy.c. The system loses 65 kJ of energy and the surroundings gain 65 kJ of energy.d. The system gains 65 kJ of energy and the surroundings lose 65 kJ of energy.

###### FREE Expert Solution

Recall that the energy flow between the system and surroundings:

$\overline{){\mathbf{∆}}{{\mathbf{E}}}_{{\mathbf{system}}}{\mathbf{=}}{\mathbf{∆}}{{\mathbf{E}}}_{{\mathbf{surroundings}}}}$
