Consider an 8259A PIC. At time 1 ns, 3 ns and 5 ns three interrupts have come via IR2, IR0 and
IR4, respectively. The peripheral is operating in fixed-priority mode. Each interrupt takes 10ns to
process. Now describe the functions of each component to handle the entire interrupt procedure.

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.
