A 025l container is initially filled with air at stp a, Ask an Expert

Academics

A 0.25L container is initially filled with air at STP. A piston compresses it adiabatically to a volume of 12.0% of the original volume. The air may be treated as an ideal gas with Î³ = 1.40 .

(a) Calculate the final temperature and pressure.

(b) Sketch a pV-diagram for this process. On this diagram also draw the isotherms for the initial and final temperatures.
