What's the meaning of life? like in your opinion. For example, does it even matter cause if I die it would be a small wave on the earth with all the other waves and won't really affect anything at all since the universe is so huge and many things on this earth would also be dead. Unless we are all just in a complex simulation like the matrix or something cause I don't know kind of weird to think about. (not a serious question just got really bored) :)

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.
