- Calculate the pressure when the gas expanded to 0.08 cubic meters:
paVa1.2=pbVb1.2, pb=pa(VbVa)1.2=3.926 bar, or 3.926⋅105 Pa.2. The work in the process is
W=∫abpdV=∫abV1.2constdV=−∫ab0.2V0.2const= =−0.2Vb0.2const+0.2Va0.2const= =−0.2Vb0.2pbVb1.2+0.2Va0.2paVa1.2=0.2paVa−pbVb=15476 J.3. The process on p-V diagram looks like
