The first law of thermodynamics states that. Is this also a statement of the principle of conservation of energy?

Yes, the heat added and the change in internal energy of the gas equal the work done by the piston.

Yes, the heat that flows into the system is used to change the internal energy of the gas and becomes work done by the piston.

No, the heat that is added to the system is only used to do work.

No, the change in internal energy is the energy lost in the system.

First law of thermo = principle of law of conservation.

Energy in an isolated system is constant, and energy can be transformed from one form to another, but energy cannot be created or destroyed.

In other words, the internal energy of a system is constant.
