8.24 The switch in Fig. 8.77 moves from position A to
position B at i = 0 (please note that the switch must
connect to point B before it breaks the connection at
A, a make-before-break switch). Determine i(t) for
1> 0.

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.
