The figure below shows four different processes that obey the first law of thermodynamics. The blocks on the arrows indicate units of energy. The arrow heads do not count for a unit of energy, so that in Figure A, the arrow for Work represents 4 units of energy. C . OF C . Etherm Etherm Etherm Each system starts out with an initial thermal energy represented by the bar chart on the left. In each case, will the final thermal energy be less than, greater than, or equal to the initial thermal energy? For process A, the final thermal energy is > the initial thermal energy. For process B, the final thermal energy is = x the initial thermal energy. For process C, the final thermal energy is v X the initial thermal energy
