Eddie and val observed the picture of an athlete running in a race. eddie stated the picture shows potential energy being transformed to kinetic energy. val stated that it shows chemical energy being transformed to mechanical energy. which best explains who is correct? a. only eddie is correct because the picture does not show a transformation that starts with chemical energy. b. only eddie is correct because the picture does not show a transformation that ends with mechanical energy. c. both eddie and val are correct because chemical energy is a type of potential energy and mechanical energy includes kinetic energy. d. both eddie and val are correct because chemical energy is a type of kinetic energy and mechanical energy includes potential energy.

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
