As a system increases in volume, it absorbs 59.0 J of energy in the form of heat from the surroundings. The piston is working against a pressure of 0.543 atm. The final volume of the system is 57.7 L. What was the initial volume of the system if the internal energy of the system decreased by 107.6 J? Volume = L

Engines for propeller-driven aircraft are limited in their maximum rotational speed by the fact that the tip speed of the propeller must not approach the speed of sound in air (mach i). taking 6 ft as a typical diameter for a propeller of a light airplane and 1100 fils as the speed of sound, find the upper limit on the rpm (revolutions per minute) of the propeller shaft.
