The change in internal energy of the system is +187 J

Explanation:

According to the first law of thermodynamics, the change in internal energy of a system is given by the equation:

$\Delta U = Q + W$

where

$\Delta U$ is the change in internal energy

Q is the heat absorbed by the system

W is the work done on the system

For the system in this problem, we have

W = +108 J is the work done on it

Q = +79 J is the hear added to it

So, the change in internal energy is

$\Delta U = 108 + 79 = +187 J$
