Describe a situation
where you know the mechanical
energy was not conserved. That is,
you know that total energy at the
start is not the same as at the end.
Why do you think it was not
conserved?
If you are struggling to think of
something, imagine a scenario where
there's some energy in the system at
the start, but then 0 J of energy in
the system by the end. Or vice versa.

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.
