In a thermodynamic process, if the internal energy of a system increases, which of the following could be true?

In a thermodynamic process, if the internal energy of a system increases, which of the following could be true?

Step 1: Understand that internal energy is the energy contained within a system.
Step 2: Know that internal energy can change due to heat transfer or work done.
Step 3: Recognize that if heat is added to the system, the internal energy increases.
Step 4: Understand that if work is done on the system (like compressing a gas), the internal energy also increases.
Step 5: Conclude that both adding heat and doing work on the system can lead to an increase in internal energy.
