ANSWER

b. adding to the internal energy only

Step-by-step explanation

The 1st Law of Thermodynamics states that the total change in the internal energy of a system, ΔU, is equal to the sum of the net heat transfer into the system, Q, and the net work done on the system, W,


\Delta U=Q+W

As we can see in this equation, we can increase the internal energy of a system by adding heat to the system or doing work to the system.

So, if heat is added to a system it will increase the internal energy of the system.

Hence, the heat goes into adding to the internal energy only.
