Kobe Gamble · Answer 1

Its A. The heat that flows into the system is transformed into work and a change in internal energy

Clayton Giles · Answer 2

The first law of thermodynamics is concerned with the conservation (not conversation) of energy. The key concept in this law is that the change in internal energy is equal to the heat that flows into the system minus the work done. This is the same as saying that if we apply heat to the system, the system may store it as internal energy or use it to perform the work. Thus, the answer to this is letter A.
