To answer this question, we need to understand the first law of thermodynamics, which states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system.

Mathematically, this is represented as ΔU = Q - W.

In this case, the volume of the system is constant (ΔV=0). This means that no work is done by the system because work (W) is defined as the force applied over a distance (or in this case, a change in volume). So, W = 0.

Therefore, the equation simplifies to ΔU = Q.

Given that the heat (Q) added to the system is 45 Joules, the change in internal energy (ΔU) of the system is also 45 Joules.

So, the value of the internal energy of the system is 45 Joules.
