2. State the various modes of operation of the BJT and briefly describe the relevant biasing
conditions, associated relationships between the terminal voltages, flow of current and
real-life applications.

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis
