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:
where
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
