Describe how capacitive and inductive sensors work and illustrate the use of each in a circuit where they are used to detect forward and return stroke limits for a double acting cylinder.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
