A a healthy diet and exercise have an impact on the overall health of the body. While your digestive and respiratory systems seem very
separate in their activities, in reality, the systems work together in
several ways. Which of these correctly pairs a body system with it's
function? All BUT ONE may apply.

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.
