Answer:

B. The system is losing 115 J, while the surroundings are gaining 115 J.

Explanation:

Internal energy is denoted by the symbol ΔE. Internal energy as the name suggests is the total energy which the body contains. It is defined as the sum of the total of kinetic energies and the potential energies of all the inside particles of the body.

For a system, internal energy can be negative as well as positive. When the system loses internal energy,it is negative and when the system absorbs internal energy it is positive.

In the context since it is given that ΔEsys = - 115 J. Therefore the system is losing internal energy of 115 J to the surrounding. The surrounding is gaining 115 J of energy because the system is surrounded by the surrounding and the internal energy is transferred to the surroundings.
